Renin-angiotensin pathway |
1. JGA cells release renin 2. renin triggers angiotensin II formation 3. angiotensin II stimulates aldosterone release 4. raises BP |
|
|
JGA cells |
1. from kidney 2. releases renin |
|
|
renin |
triggers angiotensin II formation |
|
|
angiotensin II |
stimulates aldosterone release |
|
|
aldosterone |
1. released from adrenal glands 2. distal tubules reabsorb Na+ 3. water reabsorption --> increase BP 4. regulates K+ (pees out) |
|
|
ADH |
1. made in hypothalamus 2. stored in pituitary 3. causes water reabsorption in tubules 4. raise BP 5. high levels --> vasoconstriction |
|
|
PTH |
regulates Ca (increase Ca reabsorption) and PO4-2 |
|
|
phosphate buffer system |
inside cells |
|
|
what filters through glomerulus |
small molecules, urea |
|
|
Bowman's capsule |
collects whatever filters through glomerulus |
|
|
PCT |
1. reabsorbs all nutrients 2. reabsorbs most ions 3. secretes wastes |
|
|
DCT |
1. aldosterone: rebaosrb Na, secrete K 2. PTH: reabsorb Ca |
|
|
Loop of Henle |
create osmotic gradient |
|
|
Descending Limb |
water reabsorption impermeable to water |
|
|
Ascending Limb |
NaCl reabsorption |
|
|
Collecting duct |
ADH: reabsorb H2O Urea recycling Reabsorb/secrete various ions concentrate urine
|
|
|
what drives the countercurrent multiplier? |
NaCl pump on ascending limb |
