Study Notes
Urinary System Components
- The key components of the urinary system are the kidneys, ureters, bladder, urethra, and adrenal glands.
Kidney Location
- The kidneys are located in the abdominal cavity, one on each side of the spine.
- They are situated between the levels of the 12th thoracic vertebra (T12) and the 3rd lumbar vertebra (L3).
- The left kidney is located slightly higher than the right kidney, at the level of the 1st and 2nd lumbar vertebrae (L1 and L2).
Function of the Urinary System
- The urinary system filters waste and excess fluids from the blood and regulates electrolyte levels.
- It also helps to maintain acid-base balance, regulate blood pressure, and produce hormones that help to produce red blood cells.
Importance of the Urinary System
- The proper functioning of the urinary system is crucial for removing waste and excess fluids from the body.
- If the urinary system fails, waste can build up in the body, leading to serious health problems.
Kidney Shape and Size
- The kidneys are bean-shaped organs, each about 4-5 inches (10-13 cm) long.
- They are protected by the ribs and are surrounded by a fatty layer.
Functions NOT Performed by the Urinary System
- The urinary system is NOT responsible for digestion and absorption of nutrients.
Blood Supply to the Kidneys
- The kidneys receive about 20-25% of the cardiac output, making them one of the most highly perfused organs in the body.
