Quick Reference

n. the tube that conducts urine from the bladder to the exterior. The female urethra is quite short (about 3.5 cm) and opens just within the vulva, between the clitoris and vagina. The male urethra is longer (about 20 cm) and runs through the penis. As well as urine, it receives the secretions of the male accessory sex glands (prostate and Cowper’s glands and seminal vesicles) and spermatozoa from the vas deferens; thus it also serves as the ejaculatory duct.
