What is the reason for having most of the blood volume distributed within the venous vessels at any given time?

Solution

The thin, non-elastic wall of veins (as compared to the thick, elastic, muscular walls of arteries) allows greater volumes of blood to be accommodated within the lumen of the veins. This accounts for most of the blood volume distributed within the venous vessels at any given time.
