Question

explain double circulation in humans​

Answer 1

$\huge \cal{ \underline{ \underline \color{blue}{ANSWER - }}}$

➡ The human circulatory system is a double circulatory system.

➡ The heart receives deoxygenated blood from different parts of the body, and it pumps this blood to the lungs.

➡ The oxygenated blood from the lungs returns to the heart, which is pumped again into different parts of the body by the heart.

➡ Thus, the blood passes twice through the heart making one complete round through the body. This is called double circulation.
