Definitions:

Fibrinogen

A soluble plasma protein that is converted into fibrin during blood clotting, playing a critical role in wound healing.

Fibrin

A protein formed during blood clotting that is essential for wound healing, creating a fibrous mesh that impedes blood flow.

Coagulation

The process by which blood changes from a liquid to a gel, forming a blood clot, which is an essential mechanism to prevent excessive bleeding when the vascular system is injured.

Fibrinolysis

The biological process by which fibrin clots, the products of coagulation, are broken down, thereby preventing blood clots from growing and becoming problematic.
