Blood Vessels Structure or AnatomyThe walls of the blood vessels (except capillaries) are made up of three layers from outside to inside, surrounding the central blood carrying canal called a lumen. They are:Tunica Adventitia (Tunica Externa): They form strong outer covering of arteries and ...
You see I have this blood vessels problem for a long period of time – the thing is that I even stop wearing dresses and shorts for these veins and capillaries I have over my legs so I would like to know something more about blood vessels anatomy and how come I have this blood...
In the outer cortex, xCT labeling was predominantly cytoplasmic but progressively became more membranous with distance into the lens, due to xCT insertion into the broad sides of fiber cells. In the core, xCT labeling was localized around the entire membrane of inner fiber cells suggesting a ...
This is a prompt constriction of the broken blood vessel and is the most immediate protection against blood loss. Injury stimulates pain receptors. Some of these receptors directly innervate nearby blood vessels and cause them to constrict. After a few minutes, other mechanisms take over. Injury t...

Rarely, bleeding can occur from a diverticulum when a blood vessel inside the diverticulum is weakened by the infection and ruptures. Bleeding from diverticulosis (diverticular bleeding) without the presence of diverticulitis is painless. Bleeding from diverticulosis is generally more severe and brisker ...

the blood vessel (BV) and the lymphatic vessel (LV), are histologically similar but anatomically do not share the same lumen, except at the lymphovenous valve located near the venous angle, the final junction of collecting lymph ducts, and subclavian veins4,5. LVs arise mostly from preexistin...
