Question: A patient has low platelet count. What would happen to this patient if he accidentally cuts himself?
Ans: The function of the platelet is to carry blood clotting chemical, so if a person has low platelet count and accidentally cuts himself, his wounds will recover much slower compared to normal people, as his blood clotting process will be slower.
Question: What happens when blood vessels in a person with normal platelet count are damaged?
Ans: When blood vessels in a person with normal platelet count are damaged, blood clotting will take place to heal the damaged area.
Small blood cells called platelets stick to the site of injury and spread along the surface of the blood vessel to stop the bleeding.
Chemical signals are released from small sacs inside the platelets that attract other cells to the area and make them clump together to form what is called a platelet plug.
On the surface of these activated platelets, many different clotting factors work together in a series of complex chemical reactions (known as the coagulation cascade) to form a fibrin clot. The clot acts like a mesh to stop the bleeding.
