Platelets: Fundamental in the Coagulation Process
Platelets, also known as thrombocytes, are anucleated cytoplasmic fragments present in the blood.
- Platelets have the main function of participating in the process of blood clotting, ie the formation of clots.
Main features of platelets:
- They have no core.
- They are derived from megakaryocyte cytoplasm fragments.
- They have the form of flat discs (when circulating in the blood).
- Measures between 1.5 and 3.0 micrometers in diameter (so can only be viewed on powerful microscopes).
- Have a life span of between 8 and 10 days. After that they are destroyed and removed from circulation by the spleen.

The increase in platelets in human blood is known as thrombocytosis.
- The decrease in the number of platelets in human blood is known as thrombocytopenia.
