Anti-diuretic Hormone (ADH) Flashcards
1
Q
What is the target organ of ADH?
A
The kidney
2
Q
What produces ADH?
A
The hypothalamus
3
Q
What is the role of ADH?
A
ADH adjusts the permeability of the collecting duct in the kidney and helps to conserve water in the body
4
Q
What are the effects of high levels of ADH?
A
- increases the permeability of the walls of the collecting duct
- so that more water can move by osmosis through into the tissues
- water is conserved
- urine concentrated
5
Q
What are the effects of low levels of ADH?
A
- reduces the permeability of the walls of the collecting duct
- less water can move by osmosis through into the tissues
- less water is conserved
- urine is diluted
