I would definately remove the comment about the Catholic Church 'adoption' of the Anglo-Saxon 'bleodsian' into 'blessing'. First off, the Catholic liturgy was spoken originally in Latin, so they probably wouldn't use the word 'blessing' persay. Granted, the ENGLISH word 'blessing' seems to come from the Anglo-Saxon owing to common sense, but my point is that the section concerning the Catholics apparently borrowing yet another slice of paganism for their own practices smacks a little of poor scholastics. So, I'd just like to see that section cleared up. I suppose I could do it myself, but I wouldn't be so bold as to do something so drastic on the actual article, so I'll leave it to someone more experienced. Ryan 23:38, 2 February 2006 (UTC)
From EtymOnline entry for "bless": O.E. bletsian, bledsian, Northumbrian bloedsian "to consecrate, make holy," from P.Gmc. *blothisojan "mark with blood," from *blotham "blood" (see blood). Originally a blood sprinkling on pagan altars. This word was chosen in O.E. bibles to translate L. benedicere and Gk. eulogein, both of which have a ground sense of "to speak well of, to praise," but were used in Scripture to translate Heb. brk "to bend (the knee), worship, praise, invoke blessings." Meaning shifted in late O.E. toward "to confer happiness, well-being," by resemblance to unrelated bliss. No cognates in other languages. Blessing is O.E. bledsung.

This page and White blood cells were slightly different in their presentation of percentages of blood components, leading to confusion over which was "right". Although I think the two pages are saying approximately the same thing, I have changed the "Anatomy of mammalian blood" section to state the percentages the same way that the white cell page does (i.e. 45% red, 1% white, <1% platelets and 55% plasma.)

I can explain several more types of WBCs other than leukocytes. This is overly vague and should be corrected by an expert in the field. He or she might know more than I do about this.
The white blood cells are called Leukocytes. The Leukocytes themselves can be divided further into the Granulocytes, the Lymphocytes and the Macrophages/Monocyte lineages. Granulocytes have granules when seen under light microscopy with H&E staining. They include Neutrophils (aka PMN's, "polys", or polymorphonuclear cells), Basophils and Eosinophils.

Blood circulates poisons and waste products to the liver to be metabolised into a water soluable form. These metabolites are then circulated to the kidney for elimination in the urine.

however the bodily humours article states they associated it with air JeffBobFrank 04:03, 6 Mar 2004 (UTC)
since it is associated with fire? and of course to other major elements... I have an investigatory for this, but to start with, I want to know facts about blood... Since blood contains oxygen, carbon, phorphorus and some amount of flammable materials, is it flammable too??? If not, what makes it not? or when it decomposses, is it considered flammable? and how can we make blood burst into flame? ooh... Thanks!=Phyllis
Each of the four humours of Greek medicine was associated with TWO of the four elements. The sanguine humour was hot and wet.
The "burning" of humours, as in "melancholia adusta", was the rendering of a natural temperament into something pathological, by an inappropriate use of the seven non-naturals.
It is not quite correct to suggest that the sanguine humour was particularly associated with the blood. An excess of ANY of the humours might be relieved by bloodletting in the appropriate place. Although the physical correlates of the four humours were expressions of the humours, they were not identical with them. A person might be phlegmatic by temperament, perhaps through living in a cold and wet climate, without any pathological discharge of phlegm.

Sims 207.34.120.71 21:39, 21 May 2007 (UTC) The folling reference in the artice is false and should be removed, as it constitutes libel against a religion without any reference. "Mormons believe that before Adam and Eve ate the forbidden fruit, blood was not present in their bodies. It is said to have formed after the Fall when they became mortal." There is no teaching within the LDS, Morman church that suggests this.
I agree with K. Sims, there is no reference to where this came from. Please find the reference where this is supported. As a member of the LDS church, I have never heard this belief stated as doctrine--which makes me question the validity, especially without citation.

I think that in this section that the Aztec faiths should be included, since blood was a very important part of their faith/culture. The Aztecs have been known to offer blood to their gods to since it was the most valuable resource, and that the king must offer his penis blood for the survival of the empire. Many films, documentaries and books have been written about this, including the wikipedia page

What is the marketprice for human blood targeted at consumers? 159.81.88.60 10:26, 7 May 2007 (UTC)
Generally, through a bit of sleight-of-hand accounting, blood is technically free to patients in most industrialized countries. Patients typically get charged for all of the associated services (collection costs, testing costs, shipping costs, infusion costs, etc.) instead. [3]
Winslow's book outlines some of the issues with providing a simple answer on this question. [4] I'd maybe start on page 29: "The cost of a unit of red blood cells has been notoriously difficult to calculate." The table on that page says charges in the U.S. may run about $300, and that may represent a 50% profit margin in some cases (assuming that all processed units were sold). This doesn't sound unreasonable to me: Blood Services is known to be a highly profitable branch of the American Red Cross.
A 1996 study found actual costs were in the vicinity of US$100. [5] I'd guess that those costs have increased at least 20% in the last ten years because of testing improvements and inflation.
A unit of whole blood seems to run about $300 at some non-hospital suppliers, [6] [7] which feels about right to me, based on some lab expenses from a few years ago. Better prices are almost certainly available for higher volumes.
Does anyone have any additional information, or want to sort through these links to write something useful for the article? This is a perennial question in this field, so I think we should include some information about it. WhatamIdoing ( talk) 19:45, 18 November 2007 (UTC)

When it says 45% red blood cells, 1% white, <1% platelets, and 55% plasma... is that by volume or by weight? It doesn't make this overly clear, but my guess would by volume... right?
Also, I hope you know those percentages add up to something slightly more than 101%, right? Is the white blood cell percentage supposed to be <1% as well? Are the red blood cells really 44%? If proper rounding was used to get those percentages, then I don't see how it comes out to those numbers. 71.120.201.39 18:20, 6 September 2007 (UTC)
Here's a related question that I hope someone can answer: Physiology textbooks often state that plasma is about 92% water, 8% protein, and trace amounts of other particles, including gases like O2 and CO2. However, they also often state that a liter of blood (which would be about 550 mL of plasma) can carry about 31 mL of CO2 in the dissolved form (that is, as CO2, not as bicarbonate). If that dissolved CO2 is in the plasma, it would be 5% of the plasma by volume (31mL / 550 mL = .05). So, is the answer to this discrepancy that when they say 92% water and 8% protein, they mean by weight, not by volume? Or perhaps is most of that CO2 inside red blood cells, leaving only trace amounts of CO2 in the plasma itself? Or am I missing something else??

Under Blood > In Art, there are links to artist wiki pages, but no links to their portfolios, much less examples of their art done with blood as a medium.
I hate to come to the belief Wikipedia is becoming "proper" in the Western sense, as Wiki article creation says nothing about articles of information dealing with "taboo" directly or otherwise. And Wikipedia is supposed to be a global "commons", yes?
The same concern relates to the term "war fighter" Vs. "soldier" OR "warrior".

Another opportunity is to find an image which gives a better feel for the density of rbc packing in blood. Smears and animations leave many with an impression of isolated rbcs floating in plasma. Sort of a hematocrit less than 1%. Instead, blood is really a wall to wall pile of red blood cells. Like this. I don't immediately see a CC image, but with several universities doing blood simulations, it should be straightforward to obtain one. The concept of blood carrying oxygen using red blood cells makes much more sense when you realize blood is basically a lubricated slurry of rbcs. Currently, the images on blood cell and red blood cell have the same issue, while white blood cell is slightly better. 98.216.110.149 ( talk) 14:24, 4 December 2010 (UTC)

Does anyone know how much blood a human can loose before they die? Proportionately (i.e. 3/4 or 1/2)?
Let's say Mike over here has about 5 liters of blood in his body. He is shot and he bleeds to death. How much blood would Mike have lost before he dies?
This article doesn't even list the difference in blood volume between males and females. Men have 1.500 gallons of blood, compared to 0.875 gallons for women.

Is it correct that blood moves wastes to the intestines to be turned into feces? AxelBoldt 03:55 31 May 2003 (UTC)
Blood circulates poisons and waste products to the liver to be metabolised into a water soluable form. These metabolites are then circulated to the kidney for elimination in the urine. I am not aware of any substances brought to the intestine for elimination. 58.167.194.69 21:35, 1 June 2007 (UTC):The endotelium of the mesenteric arteries it's permeable to some particles, so, some pharmaceutical products, ions and small particles may go through the the arteries to the epithelial cells, and then to the lumen of the intestine.

however the bodily humours article states they associated it with air JeffBobFrank 04:03, 6 Mar 2004 (UTC)
since it is associated with fire? and of course to other major elements... I have an investigatory for this, but to start with, I want to know facts about blood... Since blood contains oxygen, carbon, phorphorus and some amount of flammable materials, is it flammable too??? If not, what makes it not? or when it decomposses, is it considered flammable? and how can we make blood burst into flame? ooh... Thanks!=Phyllis
Each of the four humours of Greek medicine was associated with TWO of the four elements. The sanguine humour was hot and wet.
The "burning" of humours, as in "melancholia adusta", was the rendering of a natural temperament into something pathological, by an inappropriate use of the seven non-naturals.
It is not quite correct to suggest that the sanguine humour was particularly associated with the blood. An excess of ANY of the humours might be relieved by bloodletting in the appropriate place. Although the physical correlates of the four humours were expressions of the humours, they were not identical with them. A person might be phlegmatic by temperament, perhaps through living in a cold and wet climate, without any pathological discharge of phlegm.

Sims 207.34.120.71 21:39, 21 May 2007 (UTC) The folling reference in the artice is false and should be removed, as it constitutes libel against a religion without any reference. "Mormons believe that before Adam and Eve ate the forbidden fruit, blood was not present in their bodies. It is said to have formed after the Fall when they became mortal." There is no teaching within the LDS, Morman church that suggests this.
I agree with K. Sims, there is no reference to where this came from. Please find the reference where this is supported. As a member of the LDS church, I have never heard this belief stated as doctrine--which makes me question the validity, especially without citation.

I think that in this section that the Aztec faiths should be included, since blood was a very important part of their faith/culture. The Aztecs have been known to offer blood to their gods to since it was the most valuable resource, and that the king must offer his penis blood for the survival of the empire. Many films, documentaries and books have been written about this, including the wikipedia page

What is the marketprice for human blood targeted at consumers? 159.81.88.60 10:26, 7 May 2007 (UTC)
Generally, through a bit of sleight-of-hand accounting, blood is technically free to patients in most industrialized countries. Patients typically get charged for all of the associated services (collection costs, testing costs, shipping costs, infusion costs, etc.) instead. [3]
Winslow's book outlines some of the issues with providing a simple answer on this question. [4] I'd maybe start on page 29: "The cost of a unit of red blood cells has been notoriously difficult to calculate." The table on that page says charges in the U.S. may run about $300, and that may represent a 50% profit margin in some cases (assuming that all processed units were sold). This doesn't sound unreasonable to me: Blood Services is known to be a highly profitable branch of the American Red Cross.
A 1996 study found actual costs were in the vicinity of US$100. [5] I'd guess that those costs have increased at least 20% in the last ten years because of testing improvements and inflation.
A unit of whole blood seems to run about $300 at some non-hospital suppliers, [6] [7] which feels about right to me, based on some lab expenses from a few years ago. Better prices are almost certainly available for higher volumes.
Does anyone have any additional information, or want to sort through these links to write something useful for the article? This is a perennial question in this field, so I think we should include some information about it. WhatamIdoing ( talk) 19:45, 18 November 2007 (UTC)

When it says 45% red blood cells, 1% white, <1% platelets, and 55% plasma... is that by volume or by weight? It doesn't make this overly clear, but my guess would by volume... right?
Also, I hope you know those percentages add up to something slightly more than 101%, right? Is the white blood cell percentage supposed to be <1% as well? Are the red blood cells really 44%? If proper rounding was used to get those percentages, then I don't see how it comes out to those numbers. 71.120.201.39 18:20, 6 September 2007 (UTC)
Here's a related question that I hope someone can answer: Physiology textbooks often state that plasma is about 92% water, 8% protein, and trace amounts of other particles, including gases like O2 and CO2. However, they also often state that a liter of blood (which would be about 550 mL of plasma) can carry about 31 mL of CO2 in the dissolved form (that is, as CO2, not as bicarbonate). If that dissolved CO2 is in the plasma, it would be 5% of the plasma by volume (31mL / 550 mL = .05). So, is the answer to this discrepancy that when they say 92% water and 8% protein, they mean by weight, not by volume? Or perhaps is most of that CO2 inside red blood cells, leaving only trace amounts of CO2 in the plasma itself? Or am I missing something else??

Under Blood > In Art, there are links to artist wiki pages, but no links to their portfolios, much less examples of their art done with blood as a medium.
I hate to come to the belief Wikipedia is becoming "proper" in the Western sense, as Wiki article creation says nothing about articles of information dealing with "taboo" directly or otherwise. And Wikipedia is supposed to be a global "commons", yes?
The same concern relates to the term "war fighter" Vs. "soldier" OR "warrior".

Another opportunity is to find an image which gives a better feel for the density of rbc packing in blood. Smears and animations leave many with an impression of isolated rbcs floating in plasma. Sort of a hematocrit less than 1%. Instead, blood is really a wall to wall pile of red blood cells. Like this. I don't immediately see a CC image, but with several universities doing blood simulations, it should be straightforward to obtain one. The concept of blood carrying oxygen using red blood cells makes much more sense when you realize blood is basically a lubricated slurry of rbcs. Currently, the images on blood cell and red blood cell have the same issue, while white blood cell is slightly better. 98.216.110.149 ( talk) 14:24, 4 December 2010 (UTC)

Sorry, I know this the wrong place. Feel free to redirect, if you wish.
The average human body has roughly 4500 mL (4.5 liters) of blood.
12 ounces is roughly 350 mL. So, a 12 oz. beer at 5% alcohol contains 17.5 mL of alcohol.
The concentration of alcohol in the blood after 1 12 oz. beer would therefore be 0.38% (17.5 mL / 4500 mL). But that's plainly wrong. The legal limit is 0.08%. What am I doing wrong? Strangesad ( talk) 21:54, 16 February 2013 (UTC)

This is a science related article. Science rejects creationism. So no usage of mentioning religion. There are lots of religions and various other foolish believes. Mentioning about them in a scientific article is very ironical. These blood-related believes should be collectively created as a seperate article and only a link to that article should be included in this article.
