Difference between artery and vein histologically?

arteries 've short lumen where as veins 've large lumen.


Which vessel would have a larger lumen?

The vessel with a larger lumen would be a vein, as veins have thinner walls and larger lumens compared to arteries. This allows veins to accommodate more blood flow.


Why do you say that the larger lymph vessels are comparable to veins rather than arteries?

Veins have wider lumens than arteries. Veins have thin muscular walls since low pressured blood passes through veins. the walls of the veins however have the same components as in arteries, that is, they have a muscular wall, a connective tissue wall, an endothelium and a layer of elastic tissue. Since arteries experience higher pressured blood the muscular player is much thicker than the one in the veins. therefore, the lumen of the artery is much smaller than that of the vein. Therefore, since lymphatic materials must pass through lymph vessels having the materials being somewhat large, a wider lumen is needed, like that of the veins.

What is the difference between an artery and a vein and what do they do?

Arteries are more elastic but have smaller lumen. They carry blood away from the heart. Veins are less elastic have larger lumen and have valves. They carry blood to the heart.


Why do veins have large lumen?

Since arteries are placed under high-blood pressure situations due to its function as a pumper of blood from the heart to the rest of the body, it must have thick cell walls and a regulated small lumen to maintain this movement of blood. Comparatively, the veins are under low blood pressure and so only require thin walls and an larger lumen to allow easy blood flow. They can generate most of their movement of blood back to the heart via muscle contractions and automatically closing valves.


How many layers has a vein?

veins have many thin layers with circular elastic and muscle fibres and a wide lumen


What is the central opening within a tube or vessel?

Large vein on penis what is it called?

The large veins on the penis are called the dorsal veins of the penis.


What type of veins contain valves?

In the large veins. Because in the large veins the blood must fight the gravity, the blood is flowing up, there are valves in them to prevent the blood to fall down again.


How come smooth muscle fibers of an artery do not get nutrients from lumen?

The Vasa Vasorum supply the wall of the large arteries This method to feed the smooth muscle is necessary as the endothelium covering the lumen doesn't permit the ready diffusion of nutrients from the lumen.
