Anti-Diuretic Hormone Case

In this video, I will explain the action of the Anti-Diuretic hormone (ADH). ADH is also called Vasopressin, is secreted by the pituitary gland and has the capacity to control water reabsorption in the renal tubules. ADH makes sure water passes the molecule cells in the wall of the collecting duct. Most of the water in the body is filtrated by urine produced by the kidneys. The kidneys are a vital organ because of one of its function that is to regulate water balance in the blood. Its important to maintain a balance between the amount of water one gain and the amount of water one lose to avoid cell damage. This whole process is possible because of the action of the Anti-Diuretic hormone. For instance, the process starts when there is too much or too little water in blood, in which the hypothalamus detects the change and signals the pituitary gland to release the ADH, in which in the presence of too little water the kidney will reabsorb most of the water, making less water to be filtrated and as a consequence, the urine become more concentrated. On the other hand, if too much water is present, the ADH become low in the blood, facilitating water to be filtrated and the urine is more diluted. In conclusion, ADH basically plays a role in negative feedback of homeostasis of the kidney in maintaining water balance because as the level of water fall, the amount of ADH rises and so does the amount of ADH falls when the level of water rises.
