Besides minimising the loss of blood, why is it essential to plug any leak in a blood vessel? Name the component of blood which helps in this process and state how this component perform this function.
Answer
It is essential to plug any leak in a blood vessel not only to minimise the loss of blood but also to prevent the entry of germs into the body, which could cause infection. The component of blood that helps in this process is platelets. When a blood vessel is injured, platelets collect and stick at the site of injury, releasing chemicals that help in the formation of a blood clot, which seals the wound and stops bleeding.
