Platelets
Also known as: Thrombocytes
Description
Platelets are a type of very small Blood Cell manufactured from the broken fragments of the Cytoplasm of the Bone Marrow's Megakaryocytes.
Biological Function of Platelets
Cardiovascular System
Alpha-2 Adrenergic Receptors are located on Platelets (in the Blood) and stimulation of Alpha-2 Adrenergic Receptors on Platelets initiates the process of Blood Clotting.
The primary function of Platelets is to repair damaged Blood Vessels and halt Bleeding - during Bleeding, Platelets flow through the cut along with the other components of Blood. As the Platelets bump against the jagged edge of the damaged Blood Vessel, they rupture, spilling out the first chemical involved in the process of Blood Clotting - Thromboplastin.
