| Front | What happens when blood water potential decreases? |
|---|---|
| Back | - osmoreceptors in hypothalamus detect decrease in blood water potential - posterior pituitary gland stimulated to secrete more ADH - ADH increases number of aquaporins in cells in distal convoluted tubule and collecting duct - permeability of cells to water increases - more water reabsorbed by osmosis - smaller volume of more concentrated urine produced - less water loss so increase in blood water potential |
