While doing a search in the archives on deer septums, I found the question, "Has anyone looked at a live deer septum? Does it have veins in it?). One of the responses was, "According to Fred Vanderburgh there are none, veins that is. Capillaries yes, veins no.) I am not sure of the difference in a capillary and a vein. I am thinking that a capillary is a vein, just a really small one. Below are the definitions that I found. Thanks for the help.
Capillary - one of the minute blood vessels that connect arteries & veins; a tube with a small inside diameter.
Vein - a vessel that transports blood toward the heart.
Blood vessel - a tubular canal which blood circulates; an artery, vein, or capillary.

Fred's using semantics. A capillary is the smallest of all blood vessels use to supply blood to the outmost cells in the body. Spiderwebs in fact, that take blood from an artery and push it back to a vein. A vein, is a large conduit that takes blood back TO the heart. And artery takes blood FROM the heart to the capillaries.
thanks. that helps.
if the septum has no veins, but does have capilaries.....what does this mean...i guess it means if you want to show anything, it needs to be really small.
are also where exchange occurs between the actual red blood cell and the cells of the body surrounding the capillary. They are so thin, only one rbc can pass through at a time. MOst often they are found in a capillary bed, numerouse capillaries from an artery that regroup to a vein.
The septum DOES have them. I can prove it, as Ive photographed them for this very reason. I think what Fred was referring to was the overdone giant veins in some of the work we see nowadays. The soft, barely visible vesseling is there, though.
