What are the overall goals of the common pathway of coagulation?

Video transcript

Hey, everyone. Let's take a look at this question together which of the following marks the final stage of the coagulation process. Is it answer choice. A clot, retraction. Answer choice B blood vessel constriction, answer choice C platelet aggregation or answer choice D release of coagulation factors. Let's work this problem out together to try to figure out which of the following answer choices is the final stage of the coagulation process. So in order to solve this question, we have to recall what we have learned about the different stages of the coagulation process to determine which of the following is that final stage. And we can recall that following the formation of a blood clot, contraction of the platelets within the clot occurs where that contraction of the platelets within the clot refers to pulling the torn areas of the blood vessel together, which promotes wound closure, which is a crucial step in the process of hemostasis, which we note that hemostasis is the mechanism to prevent excessive bleeding. So, looking at our answer choices, which of the following marks the final stage of the coagulation process, which we know is that contraction of the platelets within the clot. So answer choice. A clot retraction is the correct answer. Since that clot retraction refers to the retraction of those torn areas of the blood vessel which are pulled together to promote wound closure. So answer choice. A is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
