Dietary TGs are digested in the stomach and duodenum into monoglycerides (MGs) and FFAs by gastric lipase, emulsification from vigorous stomach peristalsis, and pancreatic lipase. [2][3] • After initial injury, there is a brief period of arteriolar vasoconstriction, largely attributable to reflex neurogenic mechanisms and augmented by the local secretion of factors such as endothelin (a potent endothelium-derived vasoconstrictor). 1- Involves only blood clotting system. When Thrombus leads to quick death \(i.e. 3. artery or one of its branches by material (eg, thrombus, tumor, air, or fat) that originated elsewhere in the body. A thrombus is made up of fibrin, platelets and red blood cell and few inflammatory cells.
