-ADH- anti diuretic hormone
- ADH is produce in a region of the brain known as the hypothalamus, flows through the bloodstream and its target is the kidney (flow through like all hormones)
- the effect of ADH is to control and alter the composition or the quantity of water in the blood
-ADH has the ability to make the blood more or less concentrated- the tissue fluid is isotonic to the cytoplasm of the cell [role of ADH]
-ADH targets the collecting duct
- the effect of ADH is that it allows more water to come out of the collecting duct
- the collecting duct is responsible for the water to be selectively reabsorbed into the blood
-possible to increase the amount of water going into the blood by applying the ADH in
- ADH makes the collecting duct wall more pores
--> more water can escape from the collecting duct and the water can go back into the blood
- the consequence of ADH secretion is that the urine coming from the nephron would be more concentrated and would have a lower volume, the urine becomes more concentrated
