Question

Which of the following are the smallest venous vessels?
A) large veins
B) venules
C) medium veins
D) arteriovenules
E) venous valves

Accepted Answer

Venules are the smallest venous vessels, ranging in size from 8-100 micrometers in diameter. Large veins and medium veins are much larger, while arteriovenules are connections between arterioles and venules. Venous valves are structures found within veins, but they are not considered blood vessels themselves.
