| Question | Answer |
|---|---|
| GFR | glomerular filtration rate- 125ml per minute |
| GFR is regulated by | autoregulation, SNS, RAAS |
| tubular reabsorbtion | movement of substances from tubule lumen back to blood |
| transport maximum | max. rate at which a substance can be reabsorbed exceeded in diabetes melitus |
| ADH (vasopressin) | antidiuretic hormone released by posterior pituitary gland; inserts aquaporins in collecting duct--> water absorption |
| aldosterone | mineralocorticoid form adrenal cortex; increases NA reabsorption and K+ secretion in collecting duct/ DCT |
| tubular secretion | movement of substances from peritubular blood into tubule lumen; fine lines pH and K+ balance |
| albumin does NOT | appear in glomerular filtrate |
| formation of urine | filtration, reabsorption, secretion |
| Atrial natriuretic hormone (ANH) | Stimulates kidney tubules to secrete more sodium and thus lose more water |
| Anuria | Absence of urine |
| Oliguria | Scanty amount of urine |
| Polyuria | Unusually large amount of urine |
| Ureters functions | Drain urine from renal pelvis to urinary bladder |
| Urinary bladder functions | storage of urine before voiding, voiding |
| Urethra | Passage of urine from bladder to exterior of the body Passage of male reproductive fluid (semen) from the body |
| Cystitis | bladder infection |
| Micturition | urination |
| NAAS | inc renin release |
| ANP | dec renin release |
