Coagulation Cascade Intrinsic + Extrinsic Geeky Medics
WebInteractions of the factors involved in the extrinsic and common pathways are illustrated in Figures 34-1 and 34-2.The extrinsic pathway begins with circulating activated factor VII (VIIa) combining with tissue factor (TF) that is derived from damaged tissues or expressed on activated monocytes. WebTo sum it all up there are 3 pathways of coagulation of blood, intrinsic, extrinsic, and common pathways. The intrinsic is the longest and the extrinsic is the shortest respectively. The intrinsic and the extrinsic pathways lead to the common pathway. The most important organ is directly involved with the coagulation of blood in the liver. WebThe extrinsic pathway is activated by external trauma that causes blood to escape from the vascular system. This pathway is quicker than the intrinsic pathway. It involves factor VII. Intrinsic Pathway The intrinsic pathway is activated by trauma inside the vascular system, and is activated by platelets, exposed endothelium, chemicals, or collagen. size of royal caribbean luggage tags
