Study Notes
Urinary System Terminology
- Ur- or urin- or uro-: These terms are derived from the Greek verb ourein, which means to urinate. Urology is the study of the urinary system.
- Renal: This term is derived from ren, the Latin word for kidney.
The Urinary System
- The urinary system functions as the body's water treatment plant.
- It filters blood and collects and expels liquid waste products as urine.
The Kidneys
- The kidneys are bean-shaped organs located on either side of the vertebral column, between the 12th thoracic and 3rd lumbar vertebrae.
- The right kidney is slightly lower than the left due to the liver's position.
- Each kidney is approximately 4 inches (10 cm) long and contains many functional units.
- The kidneys receive approximately 20% of the blood pumped by the heart each minute.
Adrenal Glands
- The adrenal glands sit atop each kidney.
- These glands influence the renal system by affecting blood pressure and regulating sodium and water retention.
Blood Flow
- Waste-filled blood enters the kidneys through the renal artery, a branch of the abdominal aorta.
- Blood flows through a network of smaller blood vessels and filtration structures.
Kidney Functions
- The kidneys play a vital role in regulating four major bodily functions:
- Blood pressure
- Acid-base balance
- Red blood cell formation
- Electrolyte balance
