Study Notes
Platelet Production and Destruction
- Platelets are produced in the bone marrow through the process of thrombopoiesis.
- Old or damaged platelets are destroyed by the spleen.
Platelet Count
- The approximate number of platelets in 1 mm of blood is 200,000 to 400,000.
Blood Disorders
- The condition where the number of red blood cells (RBCs) is more than normal is called polycythemia.
Blood Clotting
- The protein that helps in blood-clotting with the help of clotting factors is fibrinogen.
- Fibrinogen is converted to fibrin, which forms a mesh that traps blood cells and platelets, creating a blood clot.
Blood Clotting Disorders
- If the process of blood-clotting delays due to the absence of blood-clotting chemicals, uncontrolled bleeding may occur.
