Urinary System Anatomy and Physiology

True or false: The urinary system includes two kidneys, two ureters, bladder, and urethra?

True or false: The kidneys are located retroperitoneally on the posterior wall of the abdomen?

True or false: An adult kidney weighs approximately 120 to 170 grams?

True or false: The right kidney is usually slightly higher than the left kidney?

True or false: The kidneys receive about 20% of the cardiac output in the resting state?

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.
