Hi, everyone. Welcome back. Our next question says, lymphatic vessels contain specialized structures called A V I B glomery C valves or D via. So let's look through these structures looking for the one that's present in lymphatic vessels. Choice. A Veli are specialized structures from the lungs. There are those tiny air sacks found at the end of the bronchial. So that's not our answer. Choice. Choice. B glome our specialized structures found in the kidneys. It's that a capillary network that helps to filter the blood as part of the process that generates urine but not what we're looking for. Then we have choice C valves and lymphatic vessels do have valves that maintain the one way flow of lymph lymph through the vessels just as valves in the blood vessels maintain unidirectional flow in the blood vessels. And then finally, choice D via are those fingerlike projections on the lining of the small intestine that increase the surface area for the absorption of nutrients, but they're not in lymphatic vessels. So not our answer. So again, the specialized structures that are lymphatic vessels contain choice C valves. See you in the next video
