a. thoroughfare channels.

b. metarterioles.

c. anastomoses.

d. venules.

Hi, everyone. Here's your next question. The naming of circulatory anastomosis is based on which the following A, the organ where they are located b the type of vessel walls, they have c the vessels they joined or d the muscle types where they are found. So in order to answer this question, of course, we first need to make sure we recall what circulatory anastomosis are. And this would be places where two blood vessels are joined. And two kind of key things to remember about them are they can join similar types of blood vessels. They can join two arteries, they can join two veins, they can even join an artery to a vein. So they can join different types of blood vessels and that they can be natural. So they're naturally occurring in the body, either they're supposed to be there. They are natural anatomical function. And why would this be the case? Well, they serve as insurance policy. If you've got two arteries serving the same area and one artery gets blocked, you don't shut down the entire circulation there, that would have drastic consequences. You've got kind of a backup. So that would be a case of naturally an anatomical occurrence that is just supposed to be there, they can also be artificial. So in the case of a blockage of an artery that doesn't have this backup, you could create an artificial anastomosis to reroute the blood flow. So when we think about how we'd want to name these, what is kind of the most important characteristic of a thing, we want to know about them. Well, we have two similar answer types. A the organ where they are located d the muscle types where they are found. Well, that kind of gives us a clue that these are not the correct answer. Our naming a system is not based on their location because that is not the most kind of informative thing about it in terms of what you'd want to call attention to same with choice B the type of vessel walls they have. Again, that's not the most important information. What would be the most important thing in trying to start with what's going on with this particular junction is choice C the vessels they joined an arterial arterial anastomosis, which is what you call the joining of two arteries is going to be very different from an arterial venous anastomosis, connecting an arterial and a venue directly bypassing the capillary system. So we have kind of three different types of anastomoses, arterio arterial venovenous and arteriovenous. So again, that naming of the circulatory nasty moses is based on choice C the vessels they joined. See you in the next video.
