The Importance of Blood Platelets
Introduction Blood platelets, also known as thrombocytes , are small, anucleated cell fragments that play a vital role in hemostasis—the process that prevents excessive bleeding when blood vessels are injured. Produced by megakaryocytes in the bone marrow through a process called thrombopoiesis , platelets act quickly to seal damaged blood vessels and promote wound healing. Their production and function depend on hormonal regulation, proper nutrition, and a healthy immune system. However, platelets can be significantly affected by various infections , including those caused by viruses, bacteria, and fungi . These infections can decrease platelet production, increase platelet destruction, or cause abnormal platelet activation, all of which pose serious health risks. How Platelets Are Formed Platelets are formed through a well-orchestrated biological process: Megakaryocytes : Large bone marrow cells that give rise to platelets by cytoplasmic fragmentation. Thrombopoiesis : The ...
