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:
Kidneys: These organs work constantly. They filter your blood and make urine, which your body removes. You have two kidneys, one on either side of the again of your abdomen, just under your rib cage. Each kidney is about as huge as your fist.
Ureters: These two skinny tubes internal your pelvis deliver urine out of your kidneys in your bladder.
Bladder: Your bladder holds urine till you’re prepared to drain it (pee). It’s hole, made of muscle, and fashioned like a balloon. Your bladder expands as it fills up. Most bladders can maintain up to two cups of urine.
Urethra: This tube consists of urine from your bladder from your body. It results in an opening to the outside of your body inside the penis (in men) or in front of the vagina.
The structure of the urethra in the human body
The structure of the urethra in the human body is mostly straightforward. It begins at the base of the penis, passes through the body, and ends up in the bladder. However, there are some interesting features of the urethra that deserve attention. First, the urethra has a distinct bulge that marks its entrance into the body. This bulge is also where the urethra splits into two branches. Second, the urethra is lined with smooth muscle, which makes it easier to pass urine. Lastly, the urethra is surrounded by a layer of fat, which helps to keep water in the bladder.
The structure of the urethra in the human body can be divided into three parts: the neck, the body and the tip. 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.
Urination
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.
Ejaculation
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.
What affects the health of the urethra in the human body?
