| Question | Answer |
|---|---|
| renin | enzyme released by juxtaglomerular cells when GFR or BP drops converts angiotensin --> angiotensin I |
| ACE | angiotensin converting enzyme; located in lung epithelium and converts angiotensin I---> angiotensin II |
| angiotensin II | potent vasoconstrictor; stimulates aldosterone and ADH secretion. KEY effecter of RAAS |
| ANP | opposes RAAS and inc NA+ and water secretion; released w/ high atrial stretch |
| ACE inhibitors lower BP primarily by | preventing conversion of angiotensin I to angiotensin II |

| UTI | most common in girls, upper UTI is in your kidneys |
| dysuria | painful urination |

| kidneys are in | flank area |
| chronic kidney disease (CKD) | loss of nephrons and declining GFR |
| hyperkalemia | inc potassium |
| uremia | toxic syndrome from severe azotemia; affects CNS, GI, and cardiovascular systems |
| azotemia | elevated blood urea nitrogen (BUN) and creatine; indicated significantly reduced GFR |
| lithrotripsy | use of shock waves to break down kidney stones in smaller pieces |
| women are more likely to get UTI because | they have shorter urethra |
