Anatomy and Functions of the Urethra

Anatomy of the Urethra

The urethra is a tube that connects the urinary bladder to the outside of the body. It serves as a passageway for urine to be eliminated from the body. In males, the urethra also serves as a passageway for semen during ejaculation.

Structure of the Urethra

Male Urethra:
- Prostatic urethra
- Membranous urethra
- Spongy (penile) urethra
Female Urethra:
- Location and length compared to male urethra

Functions of the Urethra

1. Urinary excretion: The primary function of the urethra is to allow the elimination of urine from the body.

2. Reproductive function (in males): In males, the urethra also serves as the passageway for the ejaculation of semen during sexual intercourse.

Urethral Disorders

Some common disorders associated with the urethra include urinary tract infections, urethral strictures, and urethritis. These conditions can cause discomfort and affect the normal function of the urethra.

Comparative Anatomy

Comparison of the urethra in males and females, including differences in length and function.

Key Takeaways

The urethra is a tube that connects the urinary bladder to the outside of the body. It serves as a passageway for urine elimination and, in males, for the ejaculation of semen. Understanding the structure and function of the urethra is essential for comprehending the urinary and reproductive systems.
