ADH increases the permeability of the distal tubule and collecting duct to water, leading to greater water reabsorption from the filtrate. This results in a smaller volume of more concentrated urine.
Stimulatie van osmoreceptoren kan leiden tot afscheiding van het hormoon ADH. Beschrijf en leg uit hoe de afscheiding van ADH de door de nieren geproduceerde urine beïnvloedt. (4 punten)
| Front | Stimulation of osmoreceptors can lead to secretion of the hormone ADH. Describe and explain how the secretion of ADH affects urine produced by the kidneys.( 4 marks) |
|---|---|
| Back | 1. Permeability of membrane/cells (to water) is increased; 2. More water absorbed from/leaves distal tubule/collecting duct; 3. Smaller volume of urine; 4. Urine becomes more concentrated; |
