explain the process of heart
Answers
Answer:
The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.

LONG ANSWER TYPE QUESTION
The heart is divided into four chambers and has valves that allow the blood to flow in one direction only.
The upper two chambers with relatively thin walls are called atria.
The two lower chambers with thick muscular walls are called ventricles.
The figure shows the complete circulatory system in the body.
The right atrium receives carbon dioxide-rich blood from the various parts of the body and is then moved into the right ventricle.
The right ventricle pumps the blood to the lungs, where carbon dioxide is removed and oxygen is absorbed.
The left atrium receives oxygen-rich blood as it comes back to the heart from the lungs and is pushed into the left ventricle.
The left ventricle pumps this blood to the rest of the body.
The right side of the heart is completely separated from the left side with the help of a partition called the septum. This prevents the mixing of oxygenated and de-oxygenated blood.
