1. Prevents Na and water loss
2. Acts on kidneys to reabsorb Na and water from urine back into blood. 3. increases blood osmolarity and plasma 4. Prevents excesive kidney excretion of Na 5. Prevents blood K levels from increasing. |
|
Where does ADH acT?
|
on kidney tubules and collecting ducts, making them permeable to water.
|
|
What are NPs secreted by?
|
