Answer 2

Double circulation refers to the phenomenon of our body where our blood flows through the heart twice in one cycle. Oxygenated blood comes from the lung and flows into the heart, where it surges out to the rest of the body to provide each limb with oxygen. The limbs in return diffuse their unfavorable products into the blood, and this de-oxygenated blood flows back to the heart, where it is pumped to the lung, and the lung purifies the blood through respiration, and the cycle continues.

Double circulation is quintessential for efficient energy usage. Since the oxygenated and de-oxygenated blood of our body is separated, our body parts receive high-quality blood 24/7.
