The platelets


Platelets are cellular fragments that are much smaller than blood cells, that is, smaller than red blood cells and leukocytes.

Platelets act on blood clotting. When there is a ruptured blood vessel injury, a series of events occur that prevent blood loss.

THE coagulation or clot formation, which is part of this process, occurs when filaments of a transformed plasma protein form a kind of network and impede the passage of blood.

The clot prevents bleeding, that is, blood loss that can occur on the surface of the body - for example, on the skin of the arm or hand - or on internal organs such as the stomach and intestines. As the blood vessel heals, the clot dries and is reabsorbed into the body.
