What are the functions of the renal system? - ANSWER✔✔-- fluid &
electrolyte balance/acid-base balance
- rid the body of water soluble waste products
- maintain normal blood volume and osmolarity
- production of erythropoietin
- activation of vitamin D to facilitate absorption of calcium
What are the 3 major function of the nephron? - ANSWER✔✔-- filtration of
water soluble substances
- reabsorption of filtered nutrients, water, and electrolytes

pressure - ANSWER✔✔-renin
What does renin stimulate the production of? - ANSWER✔✔-angiotensin I
and angiotensin II
causes vasoconstriction and the release of aldosterone - ANSWER✔✔-
angiotensin II
increases the reabsorption of Na++ - ANSWER✔✔-aldosterone
produced in the kidney and regulates GFR, renal vascular resistance, and
renin production - ANSWER✔✔-prostaglandins
