Question

leakage of blood from vessels reduces the efficiency of pumping system

Answer 1

Blood vessels form an essential part of the human pumping system. The blood is pumped from one part of the body to other through vessels. The blood pump throughout our body at a particular pressure. Any leakage in the blood vessels thus leads to instability in the blood pressure thus resulting in the less efficiency of our circulatory system. This type of leakage is observed in people suffering from diabetes. Thus the leakage can be prevented by 
I. Eating less sugar and artificial sweeteners. 
II. Perform vigorous exercise on regular bases to improve the circulation of blood.
