Urethra : Role of the urethra in the human body


 What is Urethra ?

Urethra is a tube that carries urine and semen from the male genitalia to the outside world.

Urethra, a duct that transmits urine from the bladder to the outside of the body at some point of urination. The urethra is held closed through the urethral sphincter, a muscular shape that facilitates keeping urine within the bladder till voiding can arise.

Because the urethra is anatomically related with the reproductive systems, its traits in men are quite distinct from the ones in ladies. The male’s urethra is ready 18 to 20 cm (7 to 8 inches) long and passes alongside the period of the penis before emptying. At its emergence from the bladder, the urethra passes thru the prostate gland, and seminal ducts from the testes enter the

urethra at every facet, making it the pathway for the transmission of semen in addition to for the discharge of urine. The male urethra may be divided into 3 sections: the prostatic urethra (the uppermost phase within the prostate), the membranous urethra (the segment in the urethral sphincter), and the spongy urethra (the lowermost and longest section within the penis). Additional sections can be identified, together with the preprostatic urethra (at the neck of the bladder) and the fossa navicularis, pendulous urethra, and bulbous urethra, all subdivisions of the spongy urethra. In addition, the male urethra may be described in phrases of a posterior region (prostatic and membranous urethras) and an anterior location (spongy urethra).

What is the urinary system made of in the human body?

The kidneys, ureters, bladder and urethra make up the urinary machine. They all work collectively to filter out, shop and put off liquid waste from your frame. Here’s what each organ does:

The neck is the section of the urethra nearest the bladder, and it is about 2.5 cm long. The body is the section of the urethra nearest the outside world and it is about 6 cm long. The tip is the section of the urethra nearest the prostate, and it is about 2 cm long.

In the anatomy typically referred to as male, there are 3 elements to the urethra:

  • The prostatic urethra: A part of the urethra that contains seminal fluid via the prostate gland to provide the semen so as to be ejaculated.

  • The membranous urethra: The short part of the urethra that transports fluids through the pelvic floor.

  • The penile urethra (additionally known as the spongy urethra or the cavernous urethra): The longest piece of the urethra. This section extends the complete duration of the penis and ends on the urethral meatus or the hole outside the body.

What is the role of the urethra in the human body?

The function of the urethra is to expel urine from the body. It is a small, muscular tube that runs from the bladder to the outside of the body. The urethra is about four inches long in males and about one and a half inches long in females. In males, the urethra also carries semen from the testicles to the outside of the body.


The urethra is the vessel through which urine passes after leaving the bladder. During urination, the smooth muscle lining the urethra relaxes in live performance with bladder contraction(s) to forcefully expel the urine in a pressurized move. Following this, the urethra re-establishes muscle tone by means of contracting the easy muscle layer, and the bladder returns to a cozy, quiescent kingdom. Urethral easy muscle cells are robotically coupled to each other to coordinate mechanical pressure and electrical signaling in a prepared, unitary style.


The male urethra is the conduit for semen during sexual intercourse. Urine is eliminated before ejaculation by pre-ejaculate fluid – called Cowper's fluid – from the bulbourethral gland.
