GNRS 582 Renal System Exam with correct
answers
functions of the kidney - CORRECT ANSWERS ✔✔· Blood pressure regulation
· pH + electrolyte regulation
· Elimination
· Metabolic activity
· RBC production
functions of nephron - CORRECT ANSWERS ✔✔1. Filters plasma at
glomerulus
2. Forms a filtrate of protein-free fluid (ultrafiltration)
3. Reabsorbs & secretes different substances along tubular structures
4. Regulates the filtrate to maintain body fluid volume, electrolyte composition,
and pH within narrow limits
where is the site of filtration - CORRECT ANSWERS ✔✔glomerulus
important neuroendocrine process that involves multiple organs: kidney, lungs,
pituitary gland, neurologic and cardiovascular system - CORRECT ANSWERS
✔✔RAAS system
increase aldosterone + ADH
, increase vasoconstriction
increase thirst
increase Na which increases H2O - CORRECT ANSWERS ✔✔angiotensin II
functions of angiotensin II - CORRECT ANSWERS ✔✔constricts resistance
vessels
acts on adrenal cortex to release aldosterone
release vasopressin
stimulates sodium transport
facilitates norepinephrine release
consistent blood flow and GFR are constantly maintained as long as the MAP
remains between 80-180
begins to fail when MAP is <80 or >180 - CORRECT ANSWERS
✔✔autoregulation
renal labs - CORRECT ANSWERS ✔✔BUN, creatinine
UA - pH, proteinuria, microalbuminuria, specific gravity, osmolality
What are the effects of decreased perfusion in the kidney? - CORRECT
ANSWERS ✔✔decreased perfusion = decreased filtration rate
