Describe the regulation of clot formation and how clots are removed

Answer 1

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.

Blood clotting is initiated when there is damage to the blood vessels. Platelets initially adhere to the cut edges to prevent further bleeding and there will be release of chemical mediators that will even more attract platelet aggregation. The external bleeding will stop if the plug formation of platelet is formed or if homeostasis is achieved.

Hemostasis involves three major processes:

1. Narrowing (constriction) of blood vessels
2. Activity of cell-like blood particles that help in blood clotting (platelets)
3. Activity of proteins found in blood that work with platelets to help the blood clot (clotting factors)
