Q

aldosterone

A

secreted by adrenal cortex (due to NA changes)

signals the nephrons in kidneys to reabsorb NA and thus water- increase osmolarity and control K levels

Q

Renin

A

secreted in kidneys d/t NA or fld volume
acts on angiotensinogen (plasma protein) conveting to angiotensin I which gets converted to angiotensin II (leads to vascular constriciton and aldosterone secretion

Q

ADH

A

antidiuretic hormone- produced in brain, stored in pituitary and released with change in osmolarity of blood
acts on tubules in kidneys (leading to more water absorption and decrease osm)
Osm too low- ADH stop and water excreted in urine

Q

BNp

A

brain natriuretic peptide
produced with increase in BV and BP
then NA resabsoprtion is inhibited and GFR increased
blood osm is decreased, urine output increased
