circulatory system mainly use to breathe in and out. —Preceding unsigned comment added by 2.218.29.200 (talk) 16:30, 12 April 2011 (UTC)[reply]

There is a link in the article that points to the circulatory system but it just redirects back to the same article, this one. Amnion (talk) 16:22, 29 September 2008 (UTC)[reply]

he had sex blue and some veins red, so I removed the color coding language in the article. Also, I think the picture would be a bit nicer if the lungs were pictured to the left of the heart. AxelBoldt 03:18 31 May 2003 (UTC)

Yes, the colour codes refer to oxygenation and deoxygenation! I forgot.

Why is it nicer to have lungs on the left? What are the differences? The ones I've seen usually place it on top, probably because of the anatomy. But if there's a good reason, I can move the lung's position in the illustration too. No problem. --Menchi 03:42 31 May 2003 (UTC)

No, I think it's ok as it is. AxelBoldt 21:00 31 May 2003 (UTC)

Why is there a (good) article on the circulatory system, and a (somewhat messy) article on circulation (Physiology)? If one insist on having both, shouldn't the last one be reduced to a short definition?--Ekko 08:48, 20 Feb 2005 (UTC)

Checking what links hkjjkll;j;ere on both articles, it seems there is enough to have two articles, one for the human.....cirulatory system, the other for animals in general. -- 70.2dick8.153.5 20:50, 20 Jun 2005 (UTC)

I agree. That's about the same idea discussed in mammilian circulation topic below. --TheLimbicOne(talk) 21:02, 29 January 2006 (UTC)[reply]

Someone has gone and put some kinda hack I havent figured out in this section: just says "Hi!!!" after wats happening the header. Not at all harmful, but could do with getting rid of.

The reference section needs some work. The only book referenced is rather sketchy; seems to be more about history than about medicine. Maybe but it has some information. Besides im learning about the circulatory system in science not medicine.\

More merge!!! Why don't we merge systemic circulation and coronary circulation? Coronary circulation is also considered as systemic circulation, so what IS the point of separating coronary from systemic? PrimroseEverdeen 10:47, 2 September 2010 (UTC)

Merge completedbyTarret 16:19, 2006 January 15

I'd like to either pull this info out to the article on open circulatory system or merge the open circulatory system article into here. --TheLimbicOne(talk) 17:58, 5 January 2006 (UTC)[reply]

Maybe. I bigger problem with the scope of the article is IMO - where is the more detailed description of the more advanced closed circulatory system, i.e. mammals and similar? That is what I expect fo find when I click the link to this article - a good overview if somewhat scetchy of heart, veins, arterys etc. That paragraph is pretty dense for laymen. Until there is a good overview of human/mammalian circulatory system I find it hard to decide whether the open circulatory system should have its own article or not. / --Habj 20:32, 6 January 2006 (UTC)[reply]

Oh absolutely there's enough info on both subjects for them to be their own articles. I just don't have my hands on that info to add right now. I'm actually leaning towards pulling "open" out of here and leaving a link. Then I'll fix all article links to here that really need to go to "open" instead. If I merge, I'd mark the open section as a stub section. --TheLimbicOne(talk) 00:41, 7 January 2006 (UTC)[reply]

All of the articles referenced in this section are stubs. Would anyone object to collecting them into this section of this article. This may enlarge this section enough to qualify as its own article. --TheLimbicOne(talk) 23:23, 28 January 2006 (UTC)[reply]

Good idea--Ekko 12:06, 29 January 2006 (UTC)[reply]

The systems of fish, amphibians, reptiles, birds and mammals show various stages of evolution. This sentence is a bit vague. Does it mean that the systems of the animals show increasing complexity or that they how one evolved from the other? PrometheusX303 18:44, 22 February 2006 (UTC)[reply]

Why is it relevant to this article that Servetus was executed for heresy? --Dcfleck 21:00, 26 February 2006 (UTC)[reply]

The reference to Servetus’s execution was simply a brief parenthetical digression. And given the historical significance of this particular execution, especially as it relates to the development of Western civilization's history of tolerance among those with differing beliefs and opinions, I thought it was justified. If however, this kind of digression is not considered appropriate for Wikipedia articles, then of course, it should be deleted. Being new to wikipedia am not always sure what is, and is not correct. So, I definitely welcome advice and constructive criticism. Delta x 02:42, 5 March 2006 (UTC)[reply]

I am confused why the mention of Cardiovascular system is mentioned in the beginning of the article as another word for Circulatory system when it is only one of many systems of circulation in the human body, I changed the first () marks to more often because of what my Human Biology proffessor said during class. --134.29.242.57 21:15, 28 June 2006 (UTC)[reply]

Seems to me that while this article does a good job of defining the different types of circulatory systems, it does very little to go in-depth with them. The section on its discovery is longer than them, for Heaven's sake. So, I propose a new section dealing with the specificities of each type of circulatory system.

This article needs a diagram of the main sections of the heart... and the lung flow. The picture it has at the moment is not labeled.

• I have created a tubemap of the circulatory system at http://www.magma.ca/~shawnhcorey/200710/1193774664.html . I did this because I thought it would be a fun thing to do. There are three versions of it: a small PNG, a large PNG, and a SVG. The SVG was created using Inkscape http://www.inkscape.org/ and has advance features; it may not be viewable with your browser. Some of it is not labeled, I couldn't label the interior of the heart, there was no room. It is a very simplistic diagram but more advance then anything I see on the page. It is copyrighted and available under the Creative Commons Attribution-Noncommercial-No Derivative Works 2.5 Generic http://www.magma.ca/~shawnhcorey/cc-by-nc-nd.html . I don't know if you can use it; I am presenting it as an option. Shawncorey 04:00, 1 November 2007 (UTC)[reply]

So blood only flows in arteries, veins, capillaries, etc.? Then what occupies the space between blood and the skin? 63.23.47.35 22:08, 21 July 2006 (UTC)[reply]

Usually fat, muscle, or other tissue I would expect. Unless you mean the vessel wall, which in that case, would be the vessel wall. Wafulz 23:16, 21 July 2006 (UTC)[reply]

So when you get cut, how come fat or lymph fluids don't flow out instead of blood? QuizQuick 00:29, 24 July 2006 (UTC)[reply]

It does - well, not fat because it's not particularly conducive to flowing. Our circulatory systems are simply extensive enough that virtually anywhere you are cut will bleed. There are, however, some exeptions - very small surface abrasions and scratches sometimes do not bleed, but instead are moist with a clear fluid: lymph. —Preceding unsigned comment added by 70.72.11.85 (talk) 04:04, 6 September 2008 (UTC)[reply]

When you get a skin cut, the blood coming out of it is usually from the capillaries, as many are very small. —Preceding unsigned comment added by 200.196.247.195 (talk) 21:39, 7 November 2008 (UTC)[reply]

How does the heart work in the open circulatory system? Wouldn't it just pump in circles near the heart? --Gbleem 15:50, 28 August 2006 (UTC)[reply]

cool

The section started with "HELLO!" written in big red font. I removed it, for it was clearly vandalism.--Crabby 20:52, 9 February 2007 (UTC)[reply]

I'm very new to actually editing but it appears that there is some irrelavent content under Open circulatory system about veins and arteries. Check the last paragraph or so... Is it fine to just go and delete something like that? 75.69.85.228 (talk) 15:35, 25 March 2009 (UTC)[reply]

Go ahead! Be bold! --Asav (talk) 12:10, 7 May 2009 (UTC)[reply]

What functions does it perform to be vital in the human body?--Josue Ramirez 23:01, 3 April 2007 (UTC)Jramirez23[reply]

The circulatory system takes blood containing nutrients and oxygen to the body's organs/ muscles/etc. Is that what you were wondering about? Asyuli4211 (talk) 14:56, 26 January 2011 (UTC)asyuli4211[reply]

The illustration is misleading in this article. The lungs are part of the pulmonary system, not the cardiovascular system. The cardiovascular and pulmonary systems together make the cardiopulmonary system. That is why I am deleting the picture. --Savant13 16:18, 23 April 2007 (UTC)[reply]

The lungs are part of the Respiratory System, and they play an important enough part in the Circulatory System to be included in the picture. —Preceding unsigned comment added by 67.169.98.50 (talk) 02:44, 19 December 2007 (UTC)[reply]

Mention what "cava" means. Jidanni 13:12, 15 July 2007 (UTC)[reply]

Is there a reason why this page is formatted in those box-esk things, as opposed to the style of most other pages? It seems rather difficult to read without text-wrapping. GromXXVII 12:24, 17 July 2007 (UTC)[reply]

I put humans above more primitive organisms, since it probably is the most interesting species to get to know the circulatory system of. Just because the system of other species are more simple, the system of humans is still more efficiently learned by simply studying it and no else.

I also moved a lot of duplicate information to the articles Systemic and Pulmonary circulations, since it's easier to improve and correct one main article than several duplicates. Mikael Häggström 14:41, 14 October 2007 (UTC)[reply]

Should the page be called the "circulatory system" or the "cardiovascular system"? Snowman (talk) 21:37, 29 November 2007 (UTC)[reply]

Circulatory. Cardiovascular would be better in a more advanced article. Most people looking for this page would go for "circulatory." I have no proof of this but, why make things more complex than absolutely necessary? 74.128.56.194 (talk) 02:52, 18 June 2011 (UTC)[reply]

Please, please, please, I beg of you, put a section stating that deoxygenated blood is not really blue, that is just the standard for diagrams that has been used for centuries. I train science teachers and hear this misconception all of the time. I'd be happy to offer my misconception podcast on this subject as one reference for this section: http://scienceinquirer.wikispaces.com/misconceptions On that page, I also have a picture of red food coloring viewed through diluted milk (very similar to skin) and it appears blue. Scitch (talk) 20:45, 1 February 2008 (UTC)[reply]

Blue blood

Just to let you know that the concern of yours has a place on Wikipedia. --Ludvikus (talk) 13:23, 23 April 2008 (UTC)[reply]

• But it's only a disambiguation page. My recollection is that it's a racist term or notion as in "blue blooded American." As such, though, it has no place in a science article. Why not start a separate "stub" on it? --Ludvikus (talk) 13:28, 23 April 2008 (UTC)[reply]

huh? —Preceding unsigned comment added by 122.55.199.7 (talk) 10:11, 14 January 2009 (UTC)[reply]

This article lacks way too many citations. --RAC e CA12 (talk) 23:39, 4 June 2009 (UTC)[reply]

Made a more accurate drawing, could need some minor fixes dough. The file is: File:Circulatory_System_en.png, also shown below; perhaps if updated some more and renamed to .svg, could replace older image 87.64.62.124 (talk) 12:26, 15 January 2010 (UTC)[reply]

Jagged 85 (talk · contribs) is one of the main contributors to Wikipedia (over 67,000 edits; he's ranked 198 in the number of edits), and practically all of his edits have to do with Islamic science, technology and philosophy. This editor has persistently misused sources here over several years. This editor's contributions are always well provided with citations, but examination of these sources often reveals either a blatant misrepresentation of those sources or a selective interpretation, going beyond any reasonable interpretation of the authors' intent. Please see: Wikipedia:Requests for comment/Jagged 85. The damage is so extensive that it is undermining Wikipedia's credibility as a source.

I was reading in the section and I found that the description of the reptiles circulatory system may need some re-wording to make it an easier, understandable read. Does anyone see how we could improve clarity?Asyuli4211 (talk) 15:01, 26 January 2011 (UTC)asyuli4211[reply]

The section marked 'Closed Cardiovascular System' under the heading 'Human Cardiovascular System' states the following: ' The heart is located in the center of the body between the two lungs. The reason that the heart beat is felt on the left side is because the left ventricle is pumping harder.' This is simply incorrect.

The heart is indeed on the left side of the body (the left lung is considerably smaller as a result; 2 lobes verses 3 in the right.). It is true that the left heart contracts with greater force than the right, but the 'right' and 'left' hearts actually sit in what is more accurately described as an 'anterior' and 'posterior (left and right, respectively) orientation. You can ask any anatomist this and they will agree. The heart is 'felt' in the left thorax between the 5th and 6ths ribs (generally) at the mid-clavicular line (near the nipple, in men) because this is where the apex of the heart essentially bumps upon the thoracic wall when it contracts. The base of the heart is considerably medial, but it projects to the left in an infero-lateral direction to the apex which is quite left-lateral of the sternal midline and this is why the heart is felt on the left side of hte body. Because it is in the left thorax.

I could cite any number of anatomy, physiology and/or cardiology texts, but I dont feel i need to.

I've removed the sentences in question. Thanks for bringing it up. mgiganteus1 (talk) 18:59, 27 March 2011 (UTC)[reply]

The cardio vascular system does not deliver nutrient TO cells. It distributes nutrients to all parts of the body where for the most part the leave the cardio vascular system and enter the interstitial fluid (which is indistinguishable from "lymph"). Nutrients are absorbed from the interstitial fluid and waste products excreted into the interstitial fluid where some of them are exchanged back into the cardio-vascular system and others are collected into lymphatic veins, filtered through lymph nodes, and then dumped back into the cardiovascular system near the core.

The lymphatic system does not and never "distributes" lymph, it collects it. The lymphatic system is important because many blood components such as tri-glycerides are too bulky to pass through capillaries and therefore are collected into lymph veins and put into circulation in the hepatic vein. When humans ingest fats they pass from the intestine directly into the interstitial system and are routed to the liver by passing through the lympatic veins into the hepatic (liver) vein.

The cardio vascular system is special in that it is pressurized (because it is mostly closed) and it distributes as well as collects. The lymphatic system is driven almost entirely by incidental motion and hydrostatic fluid pressure.

The old idea of the Artery-Vein-Heart "circulatory system" is just a relic. 76.126.215.43 (talk) 01:43, 9 May 2011 (UTC)+++++++++++++++++++++++++++++++++++++++[reply]

I do not know what is the procedure to get a site listed in the external links section. There is one good site that deals with anatomy of the circulatory sytem, i would like to include it here, it is completely free. Take a look and let me know. It's better than others already listed, in fact, first one in the list is not available any more. Thank you! Site is: www.anatronica.com
