What is heart and how it works
Hi aspirant,
Heart is a human organ which pumps blood throughout the body continuously.
Heart is made up of three layers of tissue.
1) Endocardium - Thin lining of the heart which forms the surface for the valves.
2) Myocardium - A thick layer of muscle which helps in contracting and relaxing of the valves.
3) Pericardium - A sac which surrounds the heart.
It consists of four chambers:
*****The left Ventricle
*****The right Ventricle
*****The left Atrium
*****The right Atrium
Working of Heart:
In pumping of blood throughout the body, all these four chambers contribute by contracting and relaxing alternatively for blood flow throughout the body.
I hope this information was helpful to you.
Good Luck!!
