Describe the role of ADH in regulating the water content of the blood. 1. ADH (anti - directic hormone) is produced in the brain - located in the Hypothalamus region of the brain. ADH flows through the blood stream and targets the kidneys.
2. Function of ADH: to control and alter the quantity/composition in the blood. - Making it more or less concentrated.
3. ADH targets --> collecting duct
Affect: allows more water to come out of the collecting duct. (collecting duct = where water is selectivly reabsorbed into the blood) - ADH increases the quantity of the water being removed.
4. ADH secretion = more water goes back into the blood, urine becomes more concentrated and the volume decreases.
