Platelets

What platelets do all day.

Thrombocytes, which are more commonly known as platelets.  Platelets are born in the marrow of our bones.  The megakaryocytes, which are surprisingly large cells, lose small fragments of themselves which then are released into the circulation as platelets. The platelets physical form consisted of a disk shaped collection of cell fragments, a small amount of cytoplasm all wrapped up in a plasma membrane.  Platelets are able to connect to other molecules because of the glycoproteins and proteins that are on their surface. The molecules and their platelet hitch hikers play an important role when the body deals with blood loss.

When it comes to the prevention of blood loss and remaining the bodies of homeostasis, platelets play their part by acting out two important roles.  They are able to assist in remedying the situation by creating platelet plugs, for jobs in small vessels, and helping in the formation of clots, to heal the larger damage that the body may suffer. A platelet plug is a grouping of many platelets whose purpose is to close off breaks in blood vessels. Tears and slight damage to the blood vessels happen very often so platelets play quite an important role in making sure the circulatory system runs true and avoids any and all harmful side effects such as hemorrhages.
