Platelet biology

Platelets are small, disc-shaped cells in our blood that play a crucial role in healing wounds. When a blood vessel is damaged, platelets quickly gather at the injury site and stick together to form a plug, preventing excessive bleeding. They also release chemicals that help further stimulate blood clotting and attract more platelets. This process is essential for stopping bleeding and beginning the healing process. Despite their small size, platelets are vital for maintaining proper blood flow and preventing blood loss after injuries.
