Platelets are small, colorless cell fragments that play a crucial role in blood clotting. When a blood vessel is injured, platelets rush to the site and form a plug to stop bleeding.
They also release chemicals that attract more platelets and promote the formation of a stable clot. Additionally, platelets help repair damaged blood vessels by releasing growth factors that stimulate the growth of new cells.
Without platelets, even minor injuries could cause life-threatening bleeding.
