Introduction The function of the reproductive system is human reproduction. Human reproduction results from the union of a female sex cell and a male sex cell.
Female reproductive system The Vagina Hallow, pear shaped muscular organ. Located in the anterior portion of the pelvic cavity. Three areas of the uterus: Body Isthmus Neck or cervix
Female reproductive system Fallopian Tubes Also called uterine tubes or oviducts Found laterally on either side of the uterus Move the ovum from the ovaries to the uterus
Female reproductive system Ovaries Located on either side of the uterus Attached to the uterus by the ovarian ligament Produce ova and hormones
Female reproductive system The Vagina A musculomembranous tube that extends from the uterus to the vestibule. Functions of the uterus include: Copulation Passageway for discharge of menstruation Birth canal
Female reproductive system Vulva consists of 5 organs that comprise the external female genitalia: Mons pubis Labia majoria Labia minoria Vestibule Clitoris The area between the vulva and the anus is the perineum.
Female reproductive system Breasts Mammary glands Provide milk for infants Prolactin stimulates the production of milk Menstrual Cycle The onset is called menarche. Cessation is called menopause. Repeats approximately every 28 days
Male reproductive system Purpose is to provide sperm cells to the ovum. Consists of the following: Testes and ducts Urethra Accessory glands; bulbourethral, prostate and seminal vesicles Accessory sex organs; scrotum and penis
Male reproductive system External organs External organs consist of the scrotum and the penis. Scrotum contains smooth muscle fibers that contract, allowing for viability of the spermatozoa.
Male reproductive system Internal Organs Testes (gonads)-site of development of the male reproductive cells & the hormone testosterone Epidydymis- coiled tube 13-20 feet in length, ends at the ductus deferens; maturation of sperm cells.
Male reproductive system Ductus deferens- vas deferens, it is the excretory duct of the testes Seminal vesicles- store sperm and produce semen. Prostate gland-lies below the bladder and secretes fluid into the semen.
Male reproductive system Bulbourethral gland- secrete mucous secretion into the seminal fluid before ejaculation. Urethra- extends from the bladder to the urethral orifice (meatus)
Prostate cancer warning signs The following are some potential prostate cancer warning signs or signs of BPH: incomplete emptying of the bladder dribbling difficulty starting urination reduced force of the stream frequent urination of small amounts pain with urination ejaculation pain blood in the urine
