Describe how the body adapts the solute pressure of the blood (thorough its use of ADH) after a person has drank a large volume of water.

Located at the base of the hypothalamus is the pituitary gland which contains osmoreceptor cells that sense the solute potential of the blood and release ADH in response to changes of the solute potential. If the solute potential of the blood rises these osmosreceptors become less stimulated and therefore release less ADH meaning less water will be reabsorbed in the distal convoluted tubule (DCT) of the nephron i.e the urine will be more dilute.A more dilute urine means that the solute potential of the blood will fall again, this is homeostasis.(SIDE NOTE: diuresis= watery)
