Physiologists often consider capillaries and postcapillary venules together. a. What functions do these vessels share? b. Structurally, how do they differ?

Video transcript

Hey, everyone. Let's take a look at this question together which of the following blood vessels serves as an outlet or leucocytes to enter the surrounding tissues. Is it answer choice. A capillaries, answer choice B veins, answer choice, C, post capillary venues or answer choice D precapillary arterials. Let's work this problem out together to try to figure out which of the following answer choices is the correct answer. So we are looking for a blood vessel which serves as an outlet for the leucocytes to enter the surrounding tissue. And we know that another name for an outlet would be that exit, which is found at the end. So we are looking for the end of a vein where those leucocytes can enter the surrounding tissue and looking at our answer choices, which of the falling blood vessels is that end of the vein. And we know that another name for something that is found at the end of something is the prefix post, which is in answer choice C since we have post capillary venues which are found at the end of the capillaries that are responsible for connecting the capillaries to the larger veins where those leucocytes enter the surrounding tissue. So answer choice c post capillary venues is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
