Thrombocyte/Platelet Structure and Function

The video, presented by Leslie Samuel, explores the process of hemostasis, which stops blood flow after a cut. It explains the role of platelets, also known as thrombocytes, in this process. Platelets are fragments of megakaryocytes, formed in the bone marrow. They circulate in the blood and are stored in the spleen. When a blood vessel is damaged, platelets activate to stop bleeding and release growth factors for healing. The video also discusses platelet disorders like thrombocytopenia and thrombocytosis, emphasizing the need for balance in platelet count to prevent excessive bleeding or clotting.
