ADH - Anti Diuretic Hormone
Produced in the Hypothalamus (a part in the brain) - flows through the blood stream to it's target (the kidney)
- ADH - controls and alter the composition of water in blood - more or less concentrated
- Tissue is isotonic with the cytoplasm of the cell
ADH - targets the collecting duct (more accurate then kidney)
- It allows more water to come out of the collecting duct
- Collecting Duct - where water is selectively reabsorbed into the blood
- possible to increase the amount of water going into the blood by adding the hormone, ADH
- It makes the collecting duct walls more porous - so that more water can escape from the collecting duct - this water goes back into the blood
- consequence of ADH secretion - Urine coming out will be more concentrated and will have a lower volume
- ADH response to a hot day
- ADH response to a cold day
- ADH response to dehydration
