Study Notes
Urinary System Overview
- The urinary system consists of two kidneys, two ureters, a bladder, and a urethra.
- This system is essential for filtering blood, removing waste, and regulating fluid balance.
Kidney Location and Anatomy
- Kidneys are located retroperitoneally, positioned behind the peritoneum on the posterior abdominal wall.
- This placement protects them and allows for connections with other organs.
Kidney Weight
- An adult kidney typically weighs between 120 to 170 grams, indicating its size and density.
- The weight is important for understanding kidney function and possible health issues.
Kidney Positioning
- The right kidney generally sits slightly lower than the left kidney due to the presence of the liver above it.
- This anatomical difference accommodates surrounding organs and structures.
Blood Flow to Kidneys
- Approximately 20% of the cardiac output is directed to the kidneys during a resting state.
- This significant blood flow is crucial for efficient filtration and regulation of bodily fluids.
