Question

____ is the physiological process that stops bleeding at the site of an injury while maintaining blood flow in the circulation

a) Coagulation
b) Hemolysis
c) Thrombolysis
d) Vasodilation

Answer 1

Coagulation is the physiological process that stops bleeding at the site of an injury while maintaining blood flow in the circulation.

Step-by-step explanation:

The physiological process that stops bleeding at the site of an injury while maintaining blood flow in the circulation is coagulation. Coagulation is the formation of a blood clot, which involves three steps:

1. Vascular spasm: The smooth muscle in the walls of the blood vessel contracts, constricting the flow of blood.
2. Platelet plug formation: Platelets form a temporary plug to seal small openings in the vessel.
3. Coagulation: Clotting factors promote the formation of a fibrin clot, which repairs the vessel wall once the bleeding has stopped.

Coagulation is a vital part of the body's natural response to injuries to prevent excessive bleeding.
