I'm

I'm not sure why the "blue box" for the cardiovascular system was removed, but I think it does belong here, perhaps even warranting the removal of the section of the types of blood vessel. JFW | T@lk 08:20, 26 Apr 2004 (UTC)

I ran across another set of terminologies I think relate somehow to Blood_vessel#Anatomy:

• tunica interna
• tunica media
• tunica externa

I suspect that these may be archaic terms to what is described in said section. Is that correct? cq 08:10, 29 July 2005 (UTC)

They are not archaic. Every medical student learns, and got the crap bored out of them, by this stuff in histology. ps take a look at wikipedia:WikiProject Preclinical Medicine, they may have good answers to questions like yours in future.

If you have a look at Marieb, E., & Hoehn, K. (2010). Pearson International Edition: Human Anatomy and Physiology (8th Ed). San Francisco, CA: Pearson Benjamin Cummings. You will find that current medical students learn is as Tunica Interna, Tunica Media and Tunica Externa. I believe if you ask any current students you will find that they have 'the crap bored out of them' in relation to this. — Preceding unsigned comment added by 180.222.12.23 (talk) 00:46, 15 June 2011 (UTC)

Expression

"Tunica intima (the thinnest layer): a single layer of simple squamous [[in arteries) be rich in vascular smooth muscle, which controls the caliber of the vessel." ...This doesn't make sense. Not sure what it should be but definitely not that! 124.168.26.64 (talk) 23:05, 18 June 2009 (UTC)

Human blood vessels

Is this article only about human blood vessels? If so, we should state it and remove the reference to homeotherms under "Physiology", and if not, we should say what kinds of organisms' blood vessels we're talking about. What say? Figma 20:29, 9 October 2006 (UTC)

I concur; blood vessels occur not only in humans. I was seeking information differentiating "closed and open blood vessels" and fear that humans do not have both. Perhaps this article should be renamed. Esoteric Rogue (talk) 23:55, 23 October 2008 (UTC)

Avascular Redirect

The word "Avascular" redirects to this page; But the word does not mean "blood vessel". It means lacking blood vessel(s). I'm not a SME, but it seems obvious that this definition should be made clear.Bcwilmot (talk) 21:16, 13 June 2012 (UTC) oighkjbkgbjh,b,jhb b,mvhjv gyug li yg liu gli ugli li i glui g luyg lgligkuy k fygfkyug l luygl kjh hg kjhgkg g y l gj gl lyig igjbgj g — Preceding unsigned comment added by 39.32.101.189 (talk) 17:24, 6 January 2014 (UTC)

Merger proposal

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.

The result of the discussion was to merge.Iztwoz (talk) 12:12, 9 April 2014 (UTC)

I propose that vascular be merged into this article. I think that the content in the 'vascular' article is trivial and can easily be incorporated in the context of this article, within a section called 'terminology' or the like. In such section we could also explain the point raised in the previous section on this talk page. HD86 (talk) 08:10, 1 January 2014 (UTC)

• Support. We just need a way to address the terminology with regards to vascular plants. A disambguation notice at the top may be required. Alternatively, vascular should be turned into a disambiguation page. JFW | T@lk 10:49, 1 January 2014 (UTC)
• Support. 'vascular' is surely just an adjective and belongs with 'blood vessel'. or with plants in a disambiguation page. Iztwoz (talk) 11:23, 12 February 2014 (UTC)
• Support per prior reasons. CFCF (talk · contribs · email) 11:26, 12 February 2014 (UTC)

Physical model

The krogh model is a model in the area of mass transfer explaining the concentration of molecular oxygen through a cylindrical capillary tube. This model explains, among other things, drug diffusion or water transport in blood vessels. It's a good approximation but it has its flaws due to the fact that a blood vessel is surrounded by other tissue around it. Grinberg et al My area of expertise is not angiology, but I'm interested in transport phenomena. I was wondering if any would like to weight in on the inclusion of this topic to the page. Thank you.

Artery picture: Basement membrane, outside the internal elastic lamina? or inside it!

The big picture (scroll down in section Type) of the artery, capillaries, vein, shows the basement membrane outside the internal elastic lamina of the artery, but I think the BM is inside the IEL, right next to endothelium (and built by the endothelium?). I see that the big picture is taken from a textbook, and it's a wonderful picture, I like it, but I have to question that part of it, and I don't know how to edit a PNG/SVG picture. (And in the 'cross-sectional area' section of that picture, shouldn't the greater-than/lesser-than symbol be reversed?) UnderEducatedGeezer (talk) 02:02, 11 September 2020 (UTC)

The Histology at Yale site, http://medcell.med.yale.edu/histology/blood_vessels_lab.php , under 'Layers Of the Vascular Wall', says, "The tunica intima comprises the endothelium, the adjacent basement membrane, the subendothelial connective tissue, and the internal elastic lamina;..." (italics mine). And similarly at Columbia, http://www.columbia.edu/itc/hs/medical/sbpm_histology_old/lab/lab07_bloodvessels.html , "Tunica intima. This consists of the endothelial lining and its basement membrane, and a delicate layer of loose subendothelial connective tissue." And also, "In arteries and arterioles, the outer margin of the tunica intima is delimited by an internal elastic membrane." (italics mine). UnderEducatedGeezer (talk) 01:57, 11 September 2020 (UTC)
