Which blood component is primarily responsible for clotting to stop bleeding?
APlatelets
BRed blood cells
CPlasma
DWhite blood cells
Explanation
Platelets, also called thrombocytes, are small cell fragments in the blood that clump together at the site of an injury to form a clot and stop bleeding. This process, called coagulation, also involves clotting proteins in the plasma working together in a complex cascade of reactions. A low platelet count can lead to excessive bleeding or bruising, while abnormally high clotting increases the risk of dangerous blood clots.
