Transcript of Male R.S. anatomy and functions.

Male R.S. anatomy and functions.
The penis is cylindrical, it contains the urethra, and is mainly composed by sponge-like tissue that is filled with blood in order to become erect.
Its main functions are deliver semen into the vagina; another function would be held in the excretory system.
The vas deferens is an important duct of the male reproductive system, its job consists in propelling the sperm brought by the epididymis along the duct to the urethra collecting all the supplement substances found along the way to produce semen as a whole
The bladder muscles contract, and two valves open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Because it passes through the penis, the urethra is longer in men. Not filled is of the size of a pear. Its capacity is 400/600 ml.
The testes are oval shaped with an approximate size of an olive and are inside the scrotum.
Inside on each of the testes there are seminiferous tubules that are in charge to produce the sperm.

Scrotum
It is located behind and underneath the penis.
It contains and protects the testicles, blood vessels, and the spermatic cord. Also regulates temperature, by contracting when exposed to cold and relaxing when exposed to heat.
Prostate
The prostate is a gland the size of a walnut located between the bladder and the penis.
The prostate secretes fluid that nourishes and protects sperm. During ejaculation, the prostate squeezes this fluid into the urethra, and it’s expelled with sperm as semen.
Epididymis
Seminal vesicles
The epididymis is a special duct found surrounding the front part of the testicle, its function is bringing the sperm produced in the testes to the vas deferens for its future release, it´s about 7 m long in a full grown adult
