Which of the following vascular structures contains the largest proportion of the total blood volume in a normal individual?

B. Arterioles

D. Chambers of the heart

E. Pulmonary vasculature

F. Vena cavae

G. Venules and veins


veins and venules


veins and venules


Venules are small thin-walled vessels that serve to bring blood back to the heart. These vessels are highly distensible and (along with veins) contain a large fraction of the blood volume.
Veins are large diameter thin-walled vessels that bring blood back to heart. They are distensible and (in addition to venules) contain a large fraction of the blood volume.


yes number venules and veins..number2 is pulmonary circulation..remember not all blood vol is circulating.. :P


G. Venules and veins


I think it is the one it has the major transection area, so my answer is ARTERIOLES


Excuse me I meant Capillaries


Its veins and venules......veins are also known as capacitance vessels.....the reason is obvious.The nornal ratio of blood distribution in the vessels in the body is 60% in veins/venules and 40% in arteries and arterioles
