|
What does ANH stand for?
|
atrial natriuretic hormone
|
|
|
Where is ANH made?
|
Heart muscle cells of the right atrium
|
|
|
What triggers ANH to be released?
|
When right atrial cells are stretched too much by blood flooding in by vena cavas
|
|
|
What does ANH target? (2)
What does ANH command? (2) |
Posterior pituitary gland --> Stop ADH production
DCT/CD --> Stop Na+ reabsorption |
|
|
What is the effect of ANH on urine?
|
˄ Increase urine volume
˅ Decrease blood volume |
|
|
What element(s) is ANH trying to save?
|
NONE!
It wants BOTH H2O and Na+ to go with the urine and not get reabsorbed. MAIN GOAL = Reduce high blood volume |
|
|
What does ADH stand for?
|
anti-diuretic hormone
|
|
|
Where is ADH made?
|
Hypothalamus
|
|
|
Where is ADH released?
|
Posterior pituitary gland
|
|
|
What does ADH target?
|
Cells of DCT/CD
|
|
|
What does ADH command? (2)
|
Become more permeable to H2O
Form more H2O channels |
|
|
What is the effect of ADH on urine? (3)
|
˄ Increase H2O reabsorption
˄ Increase urine concentration ˅ Decrease urine volume |
|
|
What element(s) is ADH trying to save?
|
H2O
|
|
|
Where is aldosterone made?
|
Adrenal cortex of the adrenal gland
|
|
|
What does aldosterone target?
|
Cells of the DCT/CD
|
|
|
What does aldosterone command?
|
Increase Na+ reabsorption by active transport
|
|
|
What is the effect of aldosterone on urine?
|
˄ Increase Na+ reabsorption
(*H2O will follow Na+ back inside tubule if ADH is present) ˅ Decrease urine concentration Note: Aldosterone does NOT increase urine volume. |
