Urinary (Urinary system (Functions (elimination of metabolic wastes (urea,…

- - - - in males also functions as sexual organ
  - - - urea, uric acid
    - - control ion balance by excreting excess
    - - alter blood levels of H and HCO
        
        eliminates varying amounts of these ions
    - - by controlling the amount of urine output, kidneys regulate BP
    - - hormones, drugs that are not used end up as urine
  - - - calcitriol is the active form of vitamin D
        
        promotes absorption of Ca
    - - by indirectly detecting oxygen levels in blood, kidneys secrete EPO when O2 levels decrease
        
        additional blood increases amount of O2 that can be transported
    - - produce glucose from non-carbohydrate sources
- - - - urea
      - uric acid
      - creatinine
    - - water
      - ions
      - glucose
        
        glucose will appear if plasma concentration exceeds renal threshold, DM
  - - - usually through active transport
- - - - higher pressure promotes filtration through glomerular capillary walls
  - - - WBC, RBC, platelets, and large proteins
    - - smaller proteins may sneak through the membrane
        
        very small amount of protein will be part of filtrate
  - - - pressure from blood due to solutes it contains
    - - pressure in the glomerular capsule of the renal corpuscle
- - - - absorbed completely in PCT
    - - most sodium is absorbed from tubular fluid
    - - PTH promotes the absorption of calcium and secretion of phosphate
  - - - solutes pass through the epithelial cells
    - - solutes move through epithelial cells
