The correct answer is - 65% of total blood found in the venous system, and it can constrict during intense exercise or hemorrhage to keep the volume in arteries and capillaries near-normal level.

Explanation:

The venous system consists of 65% of the total blood of the body. The venous system transports the blood throughout the body and can be found the maximum part of the blood in this system.

The distribution of the blood can be change at the time of intense exercise or hemorrhage by constricting the veins to keep in capillaries and arteries to the near-normal level.

Thus, the correct answer is - 65% of total blood found in the venous system, and it can constrict during intense exercise or hemorrhage to keep the volume in arteries and capillaries near-normal level.
