a small, cell-like structure in the blood that helps in clotting and preventing excessive bleeding
What is a "platelet"?
A platelet is a small, disk-shaped cell in the blood that help with clotting to stop bleeding. When a blood vessel is injured, platelets quickly gather at the place of the injury, sticking to the damaged area and forming a plug to close the wound. They also release substances that help the clotting process by attracting more platelets. This is crucial for preventing excessive bleeding from injuries and for healing.
