What is hemostasis & how does it work?

Hemostasis is the mechanism that leads to cessation of bleeding from a blood vessel. It is a process that involves multiple interlinked steps. This cascade culminates into the formation of a “plug” that closes up the damaged site of the blood vessel controlling the bleeding. It begins with trauma to the lining of the blood vessel. Stages.

What are the stages of hemostasis?

This cascade culminates into the formation of a “plug” that closes up the damaged site of the blood vessel controlling the bleeding. It begins with trauma to the lining of the blood vessel. Stages. The mechanism of hemostasis can divide into four stages. 1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug."

What happens during the coagulation cascade of hemostasis?

Ultimately, the coagulation cascade forms a substance called fibrin. During this step, the platelet plug acts like bricks and the fibrin acts like mortar. Together, they form a solid, stable clot. The last stage of hemostasis is when your body remodels the existing clot into a fibrin clot.

What happens if you don't have normal hemostasis?

Your body naturally monitors itself for injuries, and when it detects one, it reacts quickly to take control of the situation. Without normal hemostasis, even minor injuries could cause dangerous blood loss. An example of this is hemophilia, a condition where hemostasis doesn't work properly and blood can't clot effectively.
