Study Notes
Kidney Function
- The pyramids in the kidney are responsible for filtering waste and excess fluids from the blood.
Fluid Regulation
- Kidneys regulate fluids, blood pressure, and electrolytes by controlling the amount of sodium and water reabsorption in the nephrons.
Renal Pelvis Function
- The renal pelvis collects urine from the calyces and channels it into the ureter.
Hormones in Kidney Function
- Antidiuretic hormone (ADH) helps maintain fluid balance by promoting water reabsorption in the kidneys.
- Aldosterone helps regulate electrolyte balance by stimulating sodium reabsorption and potassium excretion in the kidneys.
Urine Flow Pathway
- The correct pathway of urine flow is: minor calyces → major calyces → renal pelvis → ureter → urinary bladder → urethra.
Calyces Function
- Minor calyces collect urine from the pyramids and channel it into major calyces.
- Major calyces merge into the renal pelvis.
Kidney Regulation
- The kidneys maintain fluid and electrolyte balance through the regulation of sodium and water reabsorption, and electrolyte excretion.
- Antidiuretic hormone (ADH) impacts kidney function by regulating water reabsorption, thereby controlling the concentration of urine.
