urethra

 [u-re´thrah]
the tubular passage through which urine is discharged from the bladder to the exterior of the body. adj., adj ure´thral. The external urinary opening is called the urinary meatus. In men the urethra conveys both urine and the secretions of the reproductive organs. In women its sole function is urination. The female urethra is about 4 cm long; its opening is situated between the clitoris and the opening of the vagina. The male urethra is about 20 cm long and is narrower than that of the female. It has three sections: prostatic, membranous, and penile. It extends downward from the bladder through the prostate, which secretes into it a thin fluid. The membranous portion of the urethra receives the secretion of the bulbourethral glands. The urethra then extends down through the main body of the penis to the opening, or meatus, at the tip. Along the entire length of the passage are mucous glands.

In males, it serves as the passage for semen as well as urine. Its lining, the mucosa, is thrown into folds and contains the openings of the urethral glands.
