The urethra is the organ that carries urine from the bladder to the outside of the body.
The urinary system is responsible for filtering waste products from the blood and expelling them from the body in the form of urine. This process involves several key organs, each with a specific role:
- Kidneys: These organs filter blood and produce urine.
- Ureters: These tubes carry urine from the kidneys to the bladder.
- Bladder: This organ stores urine.
- Urethra: This tube carries urine from the bladder out of the body.
Once the urine accumulates in the bladder, the body senses the need to urinate. When urination occurs, the bladder muscles contract, forcing the urine into the urethra. The urine then passes through the urethra and is expelled from the body through an opening. In males, the urethra also serves as a pathway for semen during ejaculation.
