Talk:Vein

Phlebology section

The Phlebology section is extremely US biased and reads as an advertisement for the American College of Phlebology. I suggest to move this section to it's own page (it is now self-referent), as has been done for phlebologist. LennartVerhagen (talk) 10:40, 22 July 2015 (UTC)

Translation into Chinese Wikipedia

Venous color

There seems to be some confusion about the color of veins here. The blood within veins is definitely dark red, and the bluish color one sees is due to the way light scatters through the skin. I'm not 100% confident on the exact particulars of this phenomenon - this article covers it nicely, but I'm not expert enough to properly incorporate it here. In the meantime, I've reverted this section back to what looks like the most accurate state (it was erased some time ago, but it shouldn't have been...). Samworf (talk) 06:21, 4 June 2008 (UTC)

My veins don't look blue at all. They always looked green. Is it just blue for Anglo or northern European types, but not say, Mediterranean? Also, what colour is the vein vessel itself, empty of blood and outside of the body? 207.189.230.42 (talk) 07:19, 30 November 2008 (UTC)

Here's a good lay description for the blue/green appearance of veins. Note that it does not mention subcutaneous fat, but describes the color as a function of how light interacts with skin and blood, and throws in some psychological factors of color perception. It also stresses that the color is NOT due to the oxygen saturation of venous blood, a common misconception. SteveChervitzTrutane (talk) 08:33, 28 April 2009 (UTC)

Here is a peer-reviewed article: Appl Opt. 1996 Mar 1;35(7):1151. doi: 10.1364/AO.35.001151. Why do veins appear blue? A new look at an old question. Kienle A, Lilge L, Vitkin IA, Patterson MS, Wilson BC, Hibst R, Steiner R.. Regards GetAgrippa (talk) 02:10, 7 December 2010 (UTC)

I'm glad this article specifically mentions the falseness of blue blood. That misconception always irritates me. I even saw a show on one of the discovery channels where the host mentioned the "blue deoxygenated blood returning" through veins. Gah! 24.21.10.30 (talk) 19:43, 15 May 2009 (UTC)

Function

"Standing or sitting for a prolonged period of time can cause low venous return from venous pooling vascular shock."

Didn't flow or make sense, edited to:

Standing or sitting for a prolonged period of time can cause low venous return from venous pooling (vascular) shock.

Inherent Ventricular Assist Venous_valve?

Thanks for the insight.

Does natural contraction of skeletal muscle "massage" the vein and through the one-way mechanism of the venous valve then assist the heart?

Could a pace maker applied to skeletal muscle tissue wrapped around the largest veins provide ventricular assistance? In fact, could it continue circulation should the heart fail thus allow time for treatment and recuperation?

If a person could have a supplementary heart(s), which veins would be the best candidates? does anything happen to it

Vericuss

What the heck is a vericuss? The article says that a vericuss is the predecessor to the vein, but doesn't explain it. Also, I did a quick Google search and it sent me to a site for some teacher. I don't know the correct info, so I didn't correct it, but can someone either replace it with accurate info or give a citation? Thanks, SubstantialCitrusFruit (talk) 01:04, 9 February 2020 (UTC)

It was added about a month ago by an anonymous user, replacing a blank field. I see no results for it on Google Scholar, so I think it's probably nonsense and I've removed it. I'm not a biologist so I also don't know for sure though. --Pokechu22 (talk) 07:03, 10 February 2020 (UTC)
