The heart is one of the most important organs in the entire human body having vital functions to perform. It is nothing more than a pump, composed of muscle which pumps throughout the body, beating approximately 72 times per minute of our lives. Heart is a part of the cardiovascular system which is the transport system of the body. It performs several important functions in the body.
Functions of the heart
The heart pumps the blood, which carries all the vital nutrients which help our bodies function and removes waste products that we do not need.
Example 1: Our brain requires oxygen and glucose, which, if not received continuously, will cause it loose consciousness.
Example 2: Muscles need oxygen, glucose and amino acids, as well as the proper ratio of sodium, calcium, potassium salts in order to contract normally.
Example 3: The glands require sufficient supplies of raw materials from which they manufacture specific hormones, enzymes and other vital components that our body needs.
Example 4: Through lipoproteins it supplies fatty acids and cholesterol which is needed by each and every cell of the body.
Example 5: The oxygen supplied to the cells is used to generate energy and carbon dioxide is produced as a side product. The heart pumps the carbon dioxide rich blood through the respiratory system where exchange takes place between carbon dioxide and oxygen. The oxygenated blood is again circulated in the body.
Example 6: It carries nutrients from the Gastrointestinal tract and supplies them to all the cells. The metabolic waste products formed are sent to the liver and kidney from where they are removed out of the body.
