Answer 1

$\huge\boxed{\texttt{\fcolorbox{green}{yellow}{Heya !!!}}}$

THE BLOOD PUMPING ORGAN IN OUR BODY IS :- HEART.

IT HAS 4 CHAMBERS :-

Two atria and two ventricles.

The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. 

The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs. 

Theleft ventricle is the thickest of the heart's chambers and is responsible for pumping oxygenated blood to tissues all over the body. 

_________________

The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs.HENCE IT IS NESSCARY.
