Basic Functions of Blood

Basic functions of blood

The blood flowing inside our body, pumped by the heart, flows to all parts of the body and performs various important functions:

1. Nutritional function. Blood carries oxygen (O2) and various nutrients, gives them to tissue cells and takes carbon dioxide (CO2) and other breakdown products for removal from the body.

2. Transport function. The blood carries hormones produced by the endocrine glands to the corresponding organs, thus transmitting “molecular information” from one area to another.

3. Ability to stop bleeding. When vascular bleeding occurs, the blood sends numerous white blood cells there, causes plasma to leave the vessels, or concentrates blood platelets - platelets - at the sites of blood loss.

4. Thermoregulatory function. Blood is like a heating system as it distributes heat throughout the body.

5. pH regulator function. Blood prevents changes in the acidity of the internal environment (7.35-7.45) with the help of substances such as proteins and mineral salts.

6. Protective function. Blood transports white blood cells and antibodies that protect the body from pathogenic microorganisms.
