Question

Can you live without a heart?

Answer 1

The human heart is a muscular organ that plays a central role in the circulatory system of our body. It is located- in between the lungs, behind the breastbone, or the sternum, and slightly to the left. It supplies oxygenated blood after the purification of deoxygenated blood.

Complete answer:
The human heart is a muscular organ derived from the embryonic disc and the size is about of our fist that pumps the blood involuntarily throughout its life span. It is covered by a very thick heart wall made up of three layers. The endocardium is the inner layer, the myocardium is the middle layer and the pericardium is the outer layer.

The major functions of the heart are-
Receiving deoxygenated blood from the body tissues and supplying oxygenated blood.
Pumps, or supplies blood to various organs and tissues.
It also helps to maintain and regulate the blood pressure level in our body. It does this by providing an adequate supply of blood in our bodies.
It removes the waste products and carbon dioxide from the blood. The heart purifies the blood and makes it oxygen-rich.
We all need a pump that circulates our blood or we will die.
However, when your heart has a terminal disease that leads to cardiac failure, you need a heart transplant to replace your old pump (your own heart). Fortunately, artificial heart pumps have been developed, but they are limited by the fact that they are not as good as the healthy human heart. A mechanical heart as a transplant alternative has been developed: the mechanical heart as a transplant alternative for the heart.

Note:
Although technically, it is now possible to keep a person with a heart that is not functioning alive using a mechanical pump, this technology is limited. Only a permanent heart transplant can replace the function of your own heart. But many lives have been saved with these temporary devices (mechanical hearts) as without a heart a person could not live.
