Answer 2

Heyya!

Heart is just like a pump. it helps to pump the oxygenated and deoxygenated blood. it's function is to pump blood to all parts of the body.it pumps O2 rich blood from the lungs to all parts of the body.it also receives CO2 rich blood from all parts to the lungs for purification and this process continues. 


The heart is a pump that distributes blood to theorgans of the body. The heart is made of 4 chambers. The top 2 collecting chambers are called atria; the bottom 2 ejecting chambers are called ventricles

The right atrium receives blood deficient in oxygen from the body and sends it into the right ventricle. The right ventricle squeezes the blood out to the lungs to pick up fresh oxygen.Theoxygenated bloodreturns from the lungs to the left atrium, which then funnels the blood into the left ventricle. The left ventricle ejects the oxygenated blood into the entire body via theaorta.The heart is made of a contracting muscle that generates the force required to transport blood to all parts of the body. The muscle contracts from the bottom up to eject the blood into the aorta. The aorta branches out into a network of blood vessels that distributes blood to the organs of the body.In the heart, there are 4 valves that allow the blood to move in 1 direction only. For example, the aortic valve opens when the ventricle contracts and closes immediately when the heart relaxes, preventing the blood from returning back to the left ventricle.


Hope it helps!☺️
