moving clot
5
Q
can thrombus go to embolus?
A
yes from the pressure of blood

Clotting process
- monocytes go to area of injury in blood vessel
- covered to macrophages that engulf fat and turn to foam cells
- foam cells die and deposit under endothelium
smooth muscles go to top to form fibrous cap
- when cap ruptures it exposes atheroma and stimulate coagulation forming coronary thrombus
