Hi, everybody. Let's look at the next question. Which of the following hormones is released when the blood becomes more concentrated, a higher osmolality such as during dehydration or excessive salt intake. A Thyroxine B Oxytocin C insulin or D vasopressin. Well, this question might be a little easier if vasopressin had been listed under its other name of antidiuretic hormone. So this is indeed our answer choice. D ma suppressant or A DH decreases. You're an output by increasing water reabsorption by the kidneys. And again, it's named antidiuretic hormone can help us since a diuretic causes your body to lose more fluid. And obviously, if the blood has become more concentrated, you don't want to be losing more water from the body, you'd like to be holding on to more water. So in that case, vasopressin is released, we'll just look at our other answer choices briefly. Thyroxine is a hormone that's involved in regulating metabolism. So not our correct answer here. And choice B Oxytocin is that hormone that causes feelings of affection and sexual arousal. So, not really what we need in this situation and not our answer choice and then choice C insulin. Of course, is the hormone involved in regulating blood sugar. So, not the hormone that's released when the blood is more concentrated, that's the hormone that's released when the body has an increased need for car for sugar. So choice c not our correct answer. But again, the hormone that's released when blood becomes more concentrated. Choice d vasopressin. See you in the next video.
