Which component of blood is primarily responsible for blood clotting (coagulation) at the site of vascular injury?

💡 Solution & Explanation

Platelets, or thrombocytes, are specialized non-nucleated cell fragments derived from megakaryocytes that rapidly aggregate at sites of vascular damage to plug leaks. They work in tandem with plasma coagulation factors like fibrinogen to form stable blood clots. White blood cells primarily manage immune defense, while red blood cells handle oxygen transport across tissues.
