Urethra

The urethra is a tube-like structure that connects the urinary bladder to the external environment for the removal of urine from the body. It serves as the passageway for urine to exit the body during the process of urination.

Anatomy of the Urethra:

The urethra is different in males and females:

In Males:

• The male urethra is longer than the female urethra.
• It has three parts: prostatic, membranous, and spongy (penile) urethra.
• The prostatic urethra runs within the prostate gland.
• The membranous urethra passes through the urogenital diaphragm.
• The spongy urethra extends through the penis and opens at the external urethral orifice.

In Females:

• The female urethra is shorter than the male urethra.
• It is located anterior to the vaginal opening.
• The female urethra serves only as a passageway for urine and does not have a reproductive function.

Functions of the Urethra:
