Question

explain about human heart

Answer 1

The heart is pumping organ of our body .Human heart has four chambers , top two chambers are called atrium and bottom two chambers are called ventricles .Atrium are further divide into Left atrium and right atrium and ventricles are further divide into left ventricle and right ventricle.
Septum is a wall which divide the left and right part of heart .
Through the lungs oxygenated blood comes to heart to pump in the whole body.Oxygenated blood comes to left atrium through pulmonary veins . After left atrium the oxygenated blood enters in the left ventricle. The blood exit from left ventricle and enters to the body cells through aorta . There is diffusion in the body between oxygen and carbon dioxide .The body cells absorb oxygen from the blood .CO2 gets diffuse from the body cells and enters in the blood stream .Now the blood is deoxygenated . Then deoxygenated blood enters the heart from body through vena cava , then this deoxygenated blood enters in the right atrium to right ventricle and exit the heart through pulmonary artery.
