What part of the blood stop you from bleeding by making clots?

The part of the blood that stops you from bleeding by making clots is called platelets. Platelets are small, colorless blood cells that are produced in the bone marrow. They are responsible for stopping bleeding by forming clots that plug up damaged blood vessels. When a blood vessel is damaged, platelets stick to the damaged area and release chemicals that cause other platelets to stick together and form a clot. This clot helps to stop the bleeding and allows the blood vessel to heal.
