Back 24

d

Front 25

CF defect in transepithelial what?

Front 27

Secretion is really ?

Back 27

Na flows whose secretion?

Front 28

When penicillin was rare, patients were given PAH or probenecid (a drug used to treat gout) along with the penicillin to

Back 28

decrease penicillin secretion into urine and prolong penicillin half life in the circulation.

Front 29

intrinsic mechanism

Back 29

GTB - in response to TEMPORARY increase filtration increase reabsorption (relates to s. forces) more ater solute leaving plasma and the oncontic pressure is higher and hydrosatic pressure lower FAVOR reabsorption

Front 30

instrinsic II mechanism

Back 30

GTF signals to increased NACL delivery, MD signals glomerulus to decrease GFR,

Front 31

exrinsic factors come into play to ECflV or ECosM -

Back 31

Sympathetic,ANP, BNP

Front 32

ADH stimulated by

Back 32

Osmolarity and blood pressure

Front 33

Handling of K - 3 hormones

Back 33

3 hormones maintain normal ECF by moving K from ECF to ICF, insulin Epinephrine, (Quickly EC to IN) aldosterone

Front 34

Increase H in cells and K will come out (leak out)

Back 34

2/3 K PT, 20% TAL

Front 35

Reclaim K lose H when you're?

Back 35

Hypokalemic

Front 36

Bicarb is not done at PT

Back 36

Titratable acidity - Phosphate, sulfate buffers, H will get dumped and combine w phos buffer and bicarb gets reabsorbed. ALSO amonium from glutamine ---captures H and is excreted in urine and new bicarb made!!!

Front 37

intercalated B cells put bicarb back into circ. in state of alkalosis

Back 37
