What is the Origin of Coagulation?

The word 'coagulation' stems from the Latin verb coagulare, which translates to "to curdle" or "to congeal." The detailed understanding of the coagulation process evolved from centuries of clinical observation to the modern description of the intricate cascade of twelve distinct clotting factors. Endocrine research has since revealed that hormonal status significantly influences this system.

What is the Mechanism of Coagulation?

The process is initiated by tissue factor exposure and proceeds through a complex cascade of proteolytic enzyme activations involving numerous clotting factors. This cascade culminates in the conversion of prothrombin to thrombin, which then acts as the enzyme to transform soluble fibrinogen into a cross-linked, insoluble fibrin mesh that forms the stable clot. Hormones, particularly estrogens and androgens, can modulate the hepatic synthesis of various clotting factors, directly influencing a person's risk profile for cardiovascular events.

Coagulation

Meaning

Coagulation is the essential biological process, commonly known as blood clotting, where a cascade of biochemical reactions transforms liquid blood into a solid gel or clot. This physiological response is crucial for hemostasis, the body’s mechanism to prevent excessive blood loss following injury to the vascular system. Maintaining a delicate balance in the coagulation system is paramount for preventing both hemorrhage and pathological thrombosis.
