MICROANATOMY

Detailed explanation-1: -Platelets are irregularly shaped fragments of cells that circulate in the blood until they are either activated to form a blood clot or are removed by the spleen.

Detailed explanation-2: -Platelets are tiny, irregularly shaped blood cell pieces (called fragments) that play an important role in the making of blood clots. When an injury occurs and a blood clot is needed, the platelets become sticky and help plug the site of the injury.

Detailed explanation-3: -Platelets, or thrombocytes, are small, colorless cell fragments in our blood that form clots and stop or prevent bleeding. Platelets are made in our bone marrow, the sponge-like tissue inside our bones. Bone marrow contains stem cells that develop into red blood cells, white blood cells, and platelets.

Detailed explanation-4: -Platelets are formed when cytoplasmic fragments of megakaryocytes, which are very large cells in the bone marrow, pinch off into the circulation as they age.
