Tube conveying urine from the bladder to the external urethral orifice.
The tube that runs from the urinary bladder to the penis in the male and to the vulva in the female through which urine is excreted from the body.
A tube which takes urine from the bladder to be passed out of the body.
The tube by which urine is carried from the bladder to be excreted. In males, the urethra also carries semen; about nine inches long, it passes from the bladder through the prostate gland and through the length of the penis. In females, the urethra is only about 1 Vi inches long, exiting just above the vagina. The urethra is quite vulnerable to injury or to inflammation (urethritis), as from untreated gonorrhea, balanitis, or other infections. In males, if scarring results, the urethra can become constricted, leading to painful urination, increased likelihood of infections, and possible damage to bladder or kidneys, as well as to painful ejaculation during sex. Such constriction may need to be corrected—by dilation by a tube inserted through the urethral opening or sometimes by total surgical reconstruction. In females, the urethra is somewhat less vulnerable but more readily carries infection to the bladder and kidneys. Congenital defects involving the urethra include hypospadias and epis padias.
Small tubular structure that drains urine from the bladder, passing it to the outside. In women it is very short, located behind the pubis between the clitoris and the vaginal opening; in men it is much longer, passing from the bladder through the prostate gland into the penis, and serving as the passageway for semen during ejaculation.
The short vessel used for the purpose of eliminating or passing urine.
The tube that drains urine from the bladder out of the body. The urethra is much shorter in women than in men, which may be why women tend to experience many more urinary tract infections than men.
The narrow tube that transports urine from the bladder to be excreted by the body. In women, the urethra exits in front of the vaginal opening. In men, the urethra passes through the prostate to the penis and exits at its tip. In men the urethra also functions as the passage through which semen is ejaculated. The urethra in women is about VA to 2 inches long; in men, it is about 8 inches long, which is probably why women experience far more urinary tract infections than men.
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.
The tube which leads from the urinary bladder to the exterior, and by which the urine is voided. It is about 20 cm (8 inches) long in the male and 3-5 cm (1½ inches) long in the female. In the male it passes along the penis; in the female the urethra opens to the exterior just in front of the vagina between the labial folds.
The tube for the discharge of urine extending from the bladder to the outside. In females, its orifice lies in the vestibule between the vagina and clitoris; in males, the urethra passes through the prostate gland and the penis, opening at the tip of the glans penis. 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. Surrounding the mucosa is a lamina propria containing many elastic fibers and blood vessels, outside of which is an indefinite muscular layer.
The tube through which urine leaves the body. It empties urine from the bladder.
The tube that passes from the bladder to the outside of the body, through which urine and, in males, semen, travel.
Tube (present in both sexes) that carries urine from the bladder to be excreted; has a reproductive function in men as a channel for semen.
In women, the narrow tube that lies in front of the lower part of the vagina. The urethra carries urine from the bladder to outside the body.
The conduit through which urine is expelled from the bladder is commonly known as the urethra. This tubular passage plays a vital role in the elimination of urine, facilitating its drainage and ensuring the proper functioning of the urinary system.
The passage through which urine is expelled from the bladder varies between genders. In females, the urethra is short and opens externally in front of the vagina. In males, the urethra is notably longer; it is encompassed by the prostate gland at its upper part and extends as a channel along the length of the penis, ultimately exiting at the glans.
Urethral infections, scarring, and congenital abnormalities can affect individuals of all genders. However, these issues are notably more prevalent and significant in males compared to females.
Urethritis, the inflammation of the urethra, can result from factors like infection (such as chlamydia or gonorrhea), irritation, or minor surgical procedures. In men, this condition could potentially lead to urethral stricture, causing a narrowing in a specific portion of the urethra. Moreover, the male urethra is vulnerable to harm in accidents involving pelvic injuries, sometimes necessitating surgical intervention for repair.
In some cases, male babies may have a urethral valve, a flap-like growth originating from the inner lining of the urethra. This valve restricts the urine flow, leading to a buildup of pressure on the kidneys. This occurs as urine accumulates excessively in the bladder, ureters, and the kidney’s collecting ducts. If this urethral valve is not surgically removed, it can lead to long-term and serious kidney damage.
The tube through which urine is expelled, running from the bladder’s neck to the external urethral opening (meatus). In males, it is divided into the prostatic, membranous, and spongy or penile sections, measuring approximately 9 inches in length. The prostate gland surrounds the urethra, and in older men, it may enlarge, narrowing the urethra and causing difficulties or even an inability to urinate. This condition can be temporarily relieved by inserting a catheter into the bladder and permanently resolved through surgical removal of the prostate. In females, the urethra is approximately 1½ inches long.
