A) hemorrhoids.
B) venoconstriction.
C) vaso vasorum.
D) varicose veins.
E) venous reserve.

Accepted Answer

Varicose veins are caused by weakened valves in the superficial veins, leading to distension and twisting of the veins. Hemorrhoids are a type of varicose veins found in the anal region. Venoconstriction refers to narrowing of the veins, which is not the case in varicose veins. Vaso vasorum refers to the blood vessels that supply and nourish the walls of larger blood vessels, not related to varicose veins. Venous reserve refers to the amount of blood volume that can be stored in the veins, not related to varicose veins.
