Draw a diagram/flowchart and describe in detail the process of normal clot formation AND breakdown, including the role of factors, enzymes, plasma proteins, erythrocytes, platelets, etc. Then explain, using at least three specific examples, diseases or conditions that can affect this process, leading to the inability to clot or the abnormal formation of clots. Focus on the mechanism of each disease/condition, citing specific changes in genome, transciptoin/translation, etc.

Select the incorrect statement about hemostasis: O A. In the process of coagulation, the intrinsic and extrinsic pathways lead to the activation of plasmin, which serves to activate fibrinogen, producing fibrin fibrils. O B. In platelet plug formation, platelets begin sticking to the collagen exposed when the vessel wall was damaged. The platelets forming the plug attract more platelets to the area in a positive feedback loop. OC. Coagulation is the process of platelet plug stabilization through the formation of fibrin fibrils. O D. Vascular spasm is the initial phase of hemostasis It begins when a blood vessel is severed, resulting in a reflexive narrowing of the vessel through smooth muscle contraction.
