describe the role of ADH in regulating the water content of the blood.
-ADH- anti-diuretic hormone.
-ADH is produced in the region of the brain called the hypothalamus, it flows through the bloodstream and the target is the kidney.
-the effect of ADH is to control and alter the composition or the quantity of water in the blood.
-ADH can make the blood more or less concentrated- tissue fluid is isotonic to the cytoplasm of the cell.
-ADH targets the collecting duct- allows more water to come out of the collecting duct.
-collecting duct- where water is selectively reabsorbed into the blood.
-it is possible to increase the amount of water going into the blood by applying ADH.
-ADH makes the collecting duct balls have more pores- more water can escape from the collecting duct which goes back into the blood.
-the consequence of ADH secretion is that the urine coming from the collecting duct will be more concentrated and it will have a lower volume. (because of all the water escaping from the ADH)
