Hey, everyone. Let's take a look at this question together which of the following anti clotting agents has vaso dilatory effects. Is it answer choice. A antithrombin three answer choice B Heparin, answer choice C prostacyclin or answer choice D protein S let's work this problem out together to try to figure out which of the following answer. Choices is an anti clotting agent with vaso dilatory effects. So in order to solve this question, we have to recall what we have learned about each of the following anti clotting agents and which has those vaso dilatory effects, which we know that the vaso dilatory effects tells us that the anti clotting agent promotes the dilation of blood vessels. And we can recall that prostacyclin or P G I two inhibits platelet aggregation and promotes vasodilation and prostacyclin or PG I two acts on the smooth muscle cells in the blood vessel walls. And it also helps maintain blood vessel patency and prevent blood clot formation, which means that answer choice. C prostacyclin is the correct answer as prostacyclin is the anti clotting agent with those vaso dilatory effects. And all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
