The glomerular capillaries differ from other capillary networks in the body because they a. have a larger area of anastomosis, b. are derived from and drain into arterioles, c. are not made of endothelium, d. are sites of filtrate formation.

Welcome everyone. Our next question says which of the following capillaries are derived from and drained into arterials. A glomerular capillaries. B, coronary artery capillaries, C capillaries in the end organs or d pulmonary capillaries. Well, our answer choice here will be a, the glomerular capillaries. They do, they are derived from the afferent with an a arterials and they drain into the efferent with an e arterials. So those are capillaries that both come from and drain into arterial. When we look at choice B, coronary artery capillaries, they derive from and drain into the coronary veins. So I'll say from and two coronary veins, the capillaries in the heart, I should say. So it's a little bit of a confusing naming. So the capillaries derived from and drain to the coronary veins. The coronary arteries supply blood to the heart muscle. So coronary arteries supply blood, two heart muscles, but that's why they're not correct. They don't derive from and drain into arterials to see capillaries in the end organs is just not a specific enough answer because capillaries can be found in different end organs, each of which have different sources and destination. So it's not a specific enough answer. So that's why it's not correct. And finally, the pulmonary capillaries derived from how to say from, derive from and drain two. So they're from and two the pulmonary arteries and veins, so not a arterial. So that's why they're not the correct answer, cross that out. So again, the capillaries drive from and draining into arterials, our choice, a glomerular capillaries see you in the next video.
