1
Q

Role of the Renal System

A
  • excretion
  • water/electrolyte balance
  • pH regulation
  • control of the circulating volume
  • hormone secretion
  • gluconeogenesis
2
Q

Excretion

A
  • rid the body of water soluble wastes (urea, creatine, uric acid, etc)
  • eliminate toxins and foreign substances (drugs, pesticides)
3
Q

Electrolyte Balance

A
  • water intake = water output
  • sodium intake = sodium output
  • sodium/potassium balance
4
Q

pH Regulation

A
  • reabsorption/excretion (H+ ions and HCO3 ions)

- elimination (sulfuric and phosphoric acid)

5
Q

Control of Circulating Volume

A
  • Control of circulating volume

- Control of BP (renin-angiotensin-aldosterone system)

6
Q

Hormone Secretion

A
  • The Big 4
    1) Angiotensin II
    2) Aldosterone
    3) ADH
    4) Atrial Natriuretic Peptide
  • Erethropoietin –> RBCs
  • Calcitrol
7
Q

Gluconeogenesis

A
  • create glucose from AAs

- active during periods of prolonged fasting
