1. proteins break down
    nitrogenous waset urea ammonia and cratinine
  2. primary function of the kideneys
    is to excrete of the waste products . the kidneys also asist in regulating the bodys water electrolytes and acid base balance
  3. urinary system consits of to kidneys
    which produce urine by removing wate excess water and electrolytes from thr blood
  4. two ureters
    transfers urine from the kidneys to the bladder
  5. bladdder
    collects and stores urine
  6. urethra
    transposrts urine from the bladder to the outside of the body for elimination
  7. kidneys location
    lie behin the parietal peritoneum just below the diaphragm on each side of the vertebral columns. kidneys are dark red bean shaped organs that are 4 to 5 inches wide and about 1 inch thick
  8. right kidney
    slightly lower than the left due to the liver
  9. kidneys are surrounded and anchored in place
    by adipose tissue
  10. near the cener of the kindey medical border is a notch or indentation
    hilus where the the renal artery enters and the renal vein and the ureter exit the kidney
  11. sits on top of the kidneys
    adrenal glands
  12. adrenal glands
    secrete hormone that help control BP, HR
  13. the primary minerla corticoid secreted by the adrenal cortex
  14. the primary regulator of the aldosterone is the
    plasma potassium concentration
  15. renal capsule
    outer covering of the kidney strong layer of the connective tissue
  16. renal cortex
    directly beneath the renal capsule it contains 1.25 million renal tubes which are part of the filtration system
  17. medulla
    beneath the cortex darker color contains the triangle pyramids
  18. papilae
    narrow points of the phyramid ewmpyt urine into the calyces
  19. calcyes
    cup like extensions of the renal pelvis that guide urine into the renal pelvis
  20. renal pelvis
    expanison of the upper end of the ureter, ureter turns the drians to the finished product urine into the vladder
  21. nephrons
    each kidney contacins more than 1 million nephrons
  22. function of the nephrons
    responsible for filtering blood and processing urine
  23. 3 major functions of the nephron
    • controlling body fluids levels by selectively removing or retaining waster
    • assisting with the regulation of the PH of the blood
    • and removing toxic waste from the blood
  24. two main structures of the nephron
    renal corpuscle and the renal tubule
  25. renal corpuscle
    composed of tightly bound network of cappilarries called the glumeruli that are held inside a cuplike structure
  26. juxtaglomerular
    regulates the fiunction of each nephron
  27. glomerulus/filtration
    water and solutes (sodium and other ions nitrogren waste urea uric acid creatnine glucose and other nutrients filter through the glomurli
  28. proximal convoluted tubules/reabosrption
    water solutes
  29. henles loop/reabsorption
    sodium and chloride ions
