Platelets: Definition and Functions

KOMPAS.com There are three types of blood cells, each of which has a different function for the body, namely red blood cells, white blood cells, and platelets.

Platelets are special blood cells that control blood clotting to heal wounds and stop bleeding.

Some people have low platelet counts so they are at risk for uncontrolled bleeding.

In other cases, a person can also have too many platelets in the blood.

This condition leads to possibly life-threatening health problems associated with abnormal clotting.

Definition of platelets

Blood cells that play a role in the process of blood clotting are platelets.

Platelets have significantly more numbers (150,000 to 400,000 per cubic millimeter) than white blood cells.

However, platelets occupy a much smaller fraction of the blood volume due to their relatively small size.

Reported from Encyclopedia Britannica, Like red blood cells, platelets do not have a nucleus and are not capable of cell division (mitosis).

However, platelets have a more complex metabolism than red blood cells.
