Water is reabsorbed from the proximal convolutions by which process?
diffusion
active transport
osmosis
facilitated diffusion
osmoreceptor cells are found where?

true
false
Which hormone is produced by the osmoreceptor cells?
secretin
gastrin
CCK
ADH
Anti diuretic hormone
increases permeability of the proximal tubules to water
decreases permeability of the proximal tubules to water
increases permeability of walls of the distal convolutions to water
decreases permeability of the distal convolutions to water
ADH causes

large volume of concentrated urine
small volume of dilute urine
large volume of dilute urine
If the pituitary fails to produce ADH
it causes diabetes insipidus
the animal has to drink a lot of water
a lot of watery urine is produced
all of the options

homeostatic feedback
positive feedback
enzyme action
none of these
