- URINE: ROLE OF ADH
- When the plasma is concentrated (lack of water)
- More ADH released into blood
- When it reaches the kidney it causes the collecting duct to become more permeable
- Results in more water being kept in the body
- Very concentrated urine
- When the plasma is dilute (a lot of water)
- Less ADH released into blood
- Less reaching kidney it causes the collecting duct to become impermeable
- Results in more water leaving the body
- More dilute urine
- Concentration of our urine is controlled by a hormone ADH (anti diuretic hormone)
- ADH is produced in the pituitary gland (situated just below the brain)
- Pituitary gland monitors the concentration of the blood plasma
- Releases ADH into the bloodstream, which travels in the blood
- Pituitary gland monitors the concentration of the blood plasma
- ADH is produced in the pituitary gland (situated just below the brain)
- ADH
- Urine
- Made up of water, urea and salts
- When the plasma is concentrated (lack of water)
