Question 5

describe the process wich occours when water concentration is too low

osmoregulators in the hypothalamus detect low conc of water in blood as water moves out of osmoregulatos via osmosis.
signial sent to thirst center
pituatry galnd secreates ADH
ADH travels through blood stream to the kidneys
ADH bind to receptors on cells ling collecting duct
binding of receptors activates an enzyme that causes vesicles in cd cell linning to fuse with cell membrane inserting aquaporpherins into the cell membrane making it more periable to water.
means h2o moves from collecting duct through linning cells into the blood
conc of urine increases
