Answer 1

Hey there!


=>> =>> The functions of heart are :

1.Pumping of blood

2.Transport of food to cells

3.Transport of oxygen to cells

4.Transport of carbon dioxide to lungs.




=>> The human heart is divided into four chambers. The upper two chambers are called right and left atrium and the lower two chambers are called the right and left ventricles. Right atrium receives carbon dioxide-rich blood from the body. Blood from right atrium enters the right ventricle, which contracts and pumps the blood to the lungs.


=>> Flow of blood in the human heart

On the other hand, oxygen rich blood from the lungs returns to the left atrium. From the left atrium, blood enters left ventricle. Left Ventricle contracts and pumps the blood to all parts of the body.

Hence, the rhythmic contraction and expansion of various chambers of the heart maintains the transport of oxygen to all parts of the body.



Hope it helped!!!!!☺️

Answer 2

Main function of Heart is to pump out the blood into the blood vessels.
PUMPING ACTION OF HEART

Left atrium blood from the lungs via pulmonary vein. During this collection the left atrium relaxes. It then contracts while left ventricle expands, so blood is transferred to it. As the left ventricle contracts, the blood is then pumped out for circulation in the body. Deoxygenated blood enters to the right atrium as it expands. When the right atrium contracts the corresponding lower chamber, that is the right ventricle dilates. Deoxygenated blood thus, enters in it which inturn is pumped to lungs for oxygenation.
