Question

Intrinsic and extrinsic pathways of blood clotting are interlinked at the activation steps of which of the following factors?
A Factor IX
B Factor IV
C Factor X
D Both A and D

Answer 1

Hint:-The intrinsic pathway is enacted by an injury inside the vascular framework and is initiated by platelets, uncovered endothelium, synthetics, or collagen. This pathway is slower than the extraneous path, however more significant. It includes factors XII, XI, IX, VIII. The outward route is initiated by an outer injury that makes blood escape from the vascular framework. This pathway is snappier than the genetic pathway. It includes factor VII.

Complete Answer:-The blood coagulating course happens through two separate pathways, the natural and the outward pathway.
The external path is quicker than the usual way. It includes factor VII. The biological pathway includes factors XII, XI, IX, VIII. In a like manner pathway, the two paths together completion the path of clot creation.
The essential path has elements I (fibrinogen), II (prothrombin), V, and X. Factor Xa is the prothrombin activator.
 It changes over prothrombin into thrombin. When Factor Xa is shaped, the primary pathway starts, and blood coagulation happens.
Your circulatory framework comprises vessels called veins and supply routes, which transport blood all through your body. Blood clusters can frame in veins or corridors.
At the point when blood coagulation happens in a course, it's called a blood vessel cluster. This kind of bunch causes manifestations promptly and requires crisis treatment.
The indications of a blood vessel cluster incorporate extreme agony, loss of motion of parts of the body, or both. It can prompt coronary failure or stroke.


So, the correct answer is “ option- C”

Note:- Blood coagulation is a cluster of blood that has transformed from a fluid to a gel-like or semisolid state. Thickening is an essential cycle that can keep you from losing an excess of blood in specific examples, for example, when you're harmed or cut. At the point when a coagulation structures inside one of your veins, it won't generally break down all alone. This can be an extraordinarily challenging and even hazardous circumstance
