IMMUNOLOGY

Detailed explanation-1: -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-2: -Platelets are produced from very large bone marrow cells called megakaryocytes. As megakaryocytes develop into giant cells, they undergo a process of fragmentation that results in the release of over 1, 000 platelets per megakaryocyte.

Detailed explanation-3: -Platelets help prevent bleeding Their primary function is to prevent and stop bleeding. If a blood vessel is damaged, the body sends signals to platelets which cause them to travel to the injured area. Once the platelets arrive at the site, they clump together to form a clot that helps stop bleeding.
