Which system includes the kidneys and urethra?

The renal or urinary system is responsible for the production, storage, and elimination of urine, which is formed by the kidneys. This system includes key organs such as the kidneys, ureters, bladder, and urethra. The kidneys filter waste products and excess substances from the blood, while the urethra serves as the passage for urine to exit the body. Understanding the components of this system is crucial, especially for combat medics, as maintaining fluid and electrolyte balance is vital for patient care in various scenarios. This knowledge helps in assessing and managing renal function and urinary issues in patients effectively.
