Transcript

  • 1. Author: Shawna Miller
    Chapter Ten: The Reproductive System
  • 2. Female Reproductive System
    Provides ova(female reproductive cell)
    Provides location for fertilization/growth of baby
    Secretes female sex hormones
    Nourishes the newborns with milk produced by the breasts
  • 3. Internal Genitalia
    Ovaries(one on each side of the uterus) that produce the ova
    Estrogen and progesterone are also produced by the ovaries(primary female sex hormones)
    Fallopian tubes(uterine tubes or oviducts)
    5 and ½ inches long
    Finger-like projections at the ends called fimbriae that direct the ovum into the fallopian tube
    Conception takes place here
    Uterus: lies in the center of the pelvic cavity
    Three sections: fundus(upper), corpus(central), cervix(lower)
    Vagina: lined with mucous membrane
    Passage of menstral flow here, receives the male penis, is the birth canal
  • 4. External Genitalia
    Vulva: group of structures
    Labia majora and labia minora: folds of skin that protect the vaginal orifice and the urinary meatus.
    Clitoris: erectile tissue aroused during sexual stimulation
    Perineum: area between the vaginal orifice and the anus.
  • 5. The Breast
    Mammary glands
    Produce milk(lactation) for the newborns
    Lactiferous glands(what milk produced by)
    Nipple: where milk is carried
    Areola: pigmented area around the nipple
  • 6. Pregnancy
    Gestation: length of time a baby grows and develops in the uterus(40 weeks).
    Embryo: implantation til 8 weeks.
    Fetus: 9 weeks until birth.
    Placenta:where baby gets nourishment from
    Spongy, blood filled organ formed in the uterus.
    Also called afterbirth.
    Fetus attaches to placenta by umbilical cord.
    Amnion and chorion sacs:
    Amnion(inner) floats the fetus
    Chorion(outer) protective part that forms part of placenta.
  • 7. Labor and Delivery
    Labor: actual process of expelling the fetus from the uterus through the vagina.
    Three stages
    Dilation: uterine contractions dilate cervix
    Expulsion: birth of baby
    Placental: delivery of placenta
  • 8. Male Reproductive System
    Responsible for producing sperm(male reproductive cell)
    Secreting the male sex hormones
    Delivering sperm to the female reproductive tract
    Organs include:
    Bulbourethral glands
    Epididymis
    Penis
    Prostate gland
    Seminal vesicles
    Testes
    Vas deferens
  • 9. External organs
    Testes: responsible for producing sperm.
    Seminiferous tubules: where spermatogenesis (sperm production)takes place.
    Scrotum: a sac outside the body that holds the testes.
    Epididymis:location for sperm maturation and storage.
    Penis: male sex organ
    Glans penis- soft tip
    Prepuce- foreskin
    Ejaculation- ejection of semen
    Sphincter- closes to keep urine from escaping.
  • 10. Internal Organs
    Vas deferans: carry sperm from epididymis into pelvic cavity (2).
    Seminal vesicles: secrete fluid that nourishes the sperm (2).
    Prostate gland: important for reproduction because it secretes alkaline fluid that causes neutralizing of the pH of the urethra and vagina.
    Bulbourethralglands:also called Cowper’s glands, produce a mucuslike lubricating fluid that blends with semen and becomes part of ejaculate.
  • 11. Some Common Terms
    Cervical: pertaining to the cervix
    Hysterectomy: surgical removal of the uterus
    Mastectomy: removal of the breast
    Neonate: newborn
    Testicular: pertaining to the testes
    Aspermia: condition of no sperm
    Erectile dysfunction: inability to engage in sexual intercourse due to inability to maintain an erection (impotence)
    Chancroid: highly infectious nonsyphilitic venereal ulcer
    Castration: removal of the testicles in the male or the ovaries in the female
  • 12. Pathology
    Fibrocystic breast disease: benign cysts in the breast
    Stillbirth: birth in which a viable-aged fetus dies shortly before or at the time of delivery
    Preeclampsia: metabolic disease of pregnancy
    Fibroid tumor: benign tumor or growth that contains fiber- like tissue
    Hydrocele: accumulation of fluid around the testes or along the spermatic cord.
    Testicular torsion: a twisting of the spermatic cord
    Cryptorchidism: failure of the testes to descend into the scrotal sac before birth
  • 13. Tests and Procedures
    Digital rectal exam: manual examination for an enlarged prostate by palpating the prostate gland through the wall of the rectum
    Prostate-specific antigen(PSA): a blood test to screen for prostate cancer
    Cervical biopsy: taking a sample of tissue from the cervix to test for the presence of cancer cells.
    Mammography: using x-ray to diagnose breast disease, especially breast cancer
    Colposcopy: examination of vagina using an instrument called a colposcope
    Pap smear: test for the early detection of cancer of the cervix
  • 14. Medications
    Abortifacient: medication that terminates a pregnancy
    Oral contraceptive pills: birth control medication that uses low doses of female hormones to prevent conception by blocking ovulation
    Oxytocin: a natural hormone that begins or improves uterine contractions during labor and delivery
    Spermatocide: medication that destroys sperm
    Erectile dysfunction agents: medication that temporarily produces an erection in patients with erectile dysfunction
    Androgen therapy; replacement of male hormones to treat patients who produce insufficient hormone naturally
