The male reproductive system part2Presentation Transcript
•The Male reproductive System has @ main functions. They areto produce sperm( Male reproductive cell) and to secrete themale sex hormones.•The major organs of reproduction are located outside thebody: The penis, two testes each with an epidermis.•The external Male Reproductive organs include the penis,which contains the urethra(carries both urine and semen to theoutside of the body).•The system refers to the genitourinary system.•The internal glands of reproduction includes two seminalvesicles, two vas deferens, the prostate gland and twobulbourethral glands.
The male sex organ containing erectile tissue that is encased in skin. Delivers semen into the female vagina. The penis becomes erect during sexual stimulation, which allows it to be placed within the female for ejaculation of semen. The male urethra extends from the urinary bladder to the external opening in the penis, the urinary meatus, and serves a dual function(the elimination of urine and the ejaculation of semen. During the ejaculation process, a sphincter closes to keep urine from escaping.The Penis
Two Semi Vesicles Small glands located at the base of the urinary bladder. The vesicles secrete a glucose rich fluid that nourishes sperm. The liquid and sperm males up semen and ejaculates during stimulation or sexual intercourse.
Each vas deferens carries sperm from the epididymis up into the pelvic cavity. They travel up in the front of the urinary bladder, over the top, and then back down the posterior side of the bladder to empty into the urethra. Two vas deferens along with nerves, arteries, veins, and lymphatic vessels running between the pelvic cavity and the testes form the spermatic cord.
Prostate Gland• Located just below the urinary bladder• Surrounds the urethra and when enlarged can cause difficulty in urination.• Important for the reproductive process since it secretes an alkaline fluid that assists in keeping the sperm alive by neutralizing the ph of the urethra and vagina.
TWO BULBOURETHRAL GLANDS Known as Coniper’s Glands Two small glands located on either side of the urethra just below the prostate They produce a mucus-like lubricating fluid that joins with semen to become a part of the ejaculate.
