GROSS ANATOMY

Detailed explanation-1: -When there is an injury, platelets release molecules into the blood that help turn on clotting factors . One important clotting factor is fibrin, a long, thin, and sticky protein. When it is turned on, it forms a mesh to hold the platelet plug in place. This is called a fibrin clot.

Detailed explanation-2: -Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.

Detailed explanation-3: -Platelets help prevent bleeding Their primary function is to prevent and stop bleeding. If a blood vessel is damaged, the body sends signals to platelets which cause them to travel to the injured area. Once the platelets arrive at the site, they clump together to form a clot that helps stop bleeding.

Detailed explanation-4: -As platelets accumulate at the site, they form a mesh that plugs the injury. The platelets change shape from round to spiny, and they release proteins and other substances that entrap more platelets and clotting proteins in the enlarging plug that becomes a blood clot.

Detailed explanation-5: -Overview. Blood clotting normally occurs when there is damage to a blood vessel. Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops.
