G
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.

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


  #8

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
