What happens to the bladder and urethra during an erection?
Nothing. The bladder is essentially a bag which stores urine, it is fed by the two kidneys and it drains out along the urethra, which passes through the prostate gland, then along the length of the penis and out through the small opening in its tip. During and ejaculation sperm travels from the testes along a tube called the vas deferens until it reaches the prostate gland, here the vas deferens connects with the urethra. Put simply the prostate gland acts rather like the points system on a railway track. When the penis is soft the prostate allows liquid from the bladder to pass along the urethra and out of the penis, when the penis is erect the prostate effectively stops the flow of urine and instead allows the flow of semen into the urethra and along the penis. This mechanism prevents the two fluids from mixing, this is necessary as urine is quite effective as a spermicide.
How does prostate enlargement interfere with urination?
As the prostate gland becomes enlarged, it presses against the bladder and constricts the urethra, which is the tube that runs from the bladder through the prostate and out through the penis to remove urine from the body. As the bladder and urethra are constricted, it interferes with the easy flow of urine from the body. Not only does protate enlargement constrict the urethra, it often leads to infection of the prostate and in some serious cases operation is necessary.
Which part of the penis does semen come out?
Semen is ejaculated from the urethra, which is the tube that runs through the penis. It carries both urine and semen, but they are not expelled at the same time. The muscles in the urethra help control which substance is being released.

What portion of the urethra between the prostate gland and penis?
GROSS
What portion of the urethra is between the prostate and penis?
The prostatic or membranous urethra
What structures does the urethra travels through in males?
The male urethra is divided into threesegments.The prostatic urethra passes through the prostate gland, the urogenital diaphragm and the bulb of the urethra.The membranous urethra has the shortest length and is found between the prostatic urethra and the spongy urethra. It extends downward between the apex of the prostate and the bulb of the urethra.The spongy urethra is the longest part of the male urethra and it passes through the length of the penis, more specifically through the corpus spongiosum penis (a mass of spongy tissue surrounding the male urethra within the penis), and the glans.
What glands does the urethra pass through?
The urethra passes through the prostate and the penis in the male.
Where is a mans prostate gland located?
Only men have prostates. The prostate produces semen. It is located directly beneath the bladder and in front of the rectum. The upper portion of the urethra passes through the prostate;
How might enlargement of the prostrate gland interfere with urination or the reproductive?
The Prostate (not ProstRate no second R) is rather like a doughnut and the base of the penis passes through the center on its way out of the body. The urethra passes through the penis so as the Prostate swells it constricts around the penis, cutting off or restricting the flow of urine. If the swelling is great enough it may also slightly put pressure on the bladder, limiting its ability to hold urine.
Region of male urethra that passes through urogenital diaphragm?
There is no defined region of urethra: it begins a at the bladder and ends at the head of the penis. The external urethra, the area that you can see, is called the meatus.
What cavity is the prostate in?
The prostate lies adjacent to the bladder in the lower abdomen. The urethra passes from the bladder through the prostate gland and then to the penis. Its function is to produce semen. If the prostate is removed because of cancer (prostatectomy) the urethra is stitched to the bladder. A catheter provides the means of emptying the bladder until the stitches heal.
What are the main parts of the male reproduction system?
Prostate Urethra Vas deferens Scrotum Testes Penis Epididymis
What cause an enlarged prostate gland that caused narrowing of the urethra?
urethrostenosisThe urethra is the tube from the bladder that empties urine through the penis. The urethra goes through the prostate gland. When a prostate gland becomes enlarged, it presses on the urethra and narrows the opening, thus causes urination problems.
What are the main parts of the male reproductive system?
in human the main parts of reproductive system are1. the external genitalia (penis and vulva)2.the internal organs (gametes producing gonads)(testicles and ovaries)Penis, Vagina, Testes, Ovaries, Sperm, Egg,*These are only parts, not functions.
What is the function of the penis in the reproductive system?
In males the urethra carries semen from the ejaculatory duct outwards through the penis. The semen is directed from the reproductive organs through the vas deferens tube for semen that intersects with the urethra at the prostate gland. A valve there at the base of the urethra directs the flow of either urine or semen through the urethra and out of the meatus.
