    • reproduction

    • Female reproductive system
      to a collection of female internal & external body parts that is responsible for reproduction
    • Female cell or gamete
      egg cell (ovum)
    • main functions:
      intercourse
      pregnancy
      reproduction chid birth
      urination
      childbirth
      menstruation
    • VULVA
      the external part of the Female reproductive organs, means "covering"
    • MONS PUBIS
      the fleshy area located just above the top of the vaginal opening
    • Labia Minora
      two pairs of small skin flaps that surround the vaginal opening
      Soft inner liplike folds of tissue that surround the other sex organs
      to protect the sensitive structures within the vulva
    • Labia Majora
      two pairs of large skin Flaps that surround the vaginal opening
      Soft outer lipline folds of tissue that surround the other sex organs
      typically covered with pubic hair and contain sweat oil secreting glands
      serves several functions, including protecting the internal reproductive organs and maintaining moisture in the vulvar region
    • Clitoris
      a small censory organ that is located toward the Front of the vulva where the folds of the labia join
    • Urethra
      canal that carries urine from the bladder to outside the body
    • vagina
      about 3 to 5 inches long in a grown woman
      It has muscular walls so that it can expand contract ability to become wider and narrower allows the vagina to accommodate something as slim as a tampon and as wide as a baby
    • Purposes
      it is where the penis is inserted during sexual intercourse
      a baby taken out of a woman's body during childbirth
      it is a pathway called the birth canal
      provides the route for the menstrual blood the period to leave the body from the uterus.
    • Cervix
      means "neck”
      the opening is very small (no wider than a straw)
      During childbirth, the cervix can expand to allow a baby to pass
    • Uterus
      has a thick lining & muscular walls
      has the strongest muscles in the female body these muscles can expand and contract to accomodate a growing fetus and then help push the baby out during labor
    • FALLOPIAN TUBE
      there are 2, each attached to a side of the uterus
      the narrow tubes that are passageways From the ovaries to the uterus
    • Ovary
      they produce, store, release eggs into the Fallopian tubes in the process called ovulation
      each ovary measures about 1 1/2 to 2 inches in a grown woman
      Produces hormones (estrogen & progesterone)
    • male reproductive system
      The collection of male internal & external body parts that are responsible for reproduction
      the main function is to produce sperm and deliver it to the Female reproductive system
    • PUBERTY
      the process of physical changes through a child's body matures into an adult body capable of sexual reproduction
    • Male Puberty Starts at around 12-13 yrs old
      increase in growth rate
      alterations in behavior
      enlargement of genitals
      the appearance of secondary sexual characteristics such as Facial hair
    • SPERM male gamete
       0.002 inches (0.05 mm) size
      a healthy male can produce millions of sperm each day. The exact number can vary, but estimates range from several hundred million to over a billion sperm per day
    • PARTS OF THE SPERM
      Head contains the genetic material and an enzyme
      that helps penetrate the egg
      Midpiece packed with mitochondria to provide energy for the journey
      Tail (flagellum) propels the sperm forward
    • Semen
       a thick Fluid containing sperm & other secretions from the male reproductive system
      These fluids give nutrition & protection to the sperm to help them reach the egg for fertilization
    • TESTICLES (Testes)
      it makes sperm (testosterone)
      males begin to produce 100 million sperm a day once they reach puberty
    • testosterone
      the male sex hormone that influences sperm production causes Facial and body hair to grow, shoulders to broaden, and voice to deepen.
    • SCROTUM
      the skin that covers the testes
      helps with temp. Control
    • Penis
      the external male reproductive organ
      removes urine from the bladder and also delivers sperm to the female reproductive system
    • Foreskin
      a piece of skin that partially covers the tip of the penis at birth
    • circumcision
      is the removal of the foreskin from the tip of the penis
    • Erection
      when the penis becomes hard to firm
      the blood vessels in the penis fill blood
      the penis must be erect for ejaculation to occur
    • ejaculation
      when sperm are released from the penis
      one ejaculation contains 40-300 million sperm
      it is normal for a male to ejaculate during sleep, this is nocturnal emissions or "wet dreams”
    • Urethra
       a tube that starts at the bladder and ends at the opening of the penis
      sperm also pass through during ejaculation but not
      at the same time as urine is carried
    • EPIDIDYMIS
      a tightly coiled tube where sperm mature as they Pass through
      can be up to 20-23 Feet long
    • Vas deferens
      the next portion of a narrow tube that sperm pass through can be up to 12 inches long
    • Vasectomy
      the severing & tying off of the vas deferens
      once the vas deferens is severed, sperm will not be able to be ejaculated out of the penis
    • SEMINAL VESICLES
       Found near the base of the urinary bladder produce thick secretions that nourish the sperm and help sperm move easier (semen)
    • Prostate Gland
      about the size of a walnut
      secretes a thin milky fluid that protects the sperm from acid in the Female reproductive system
    • Cowpers Gland
       Found near the urethra below the prostate gland secretes a clear fluid that protects the sperm from acid in the male urethra
    • PATH OF SPERM TEV S PUP
      Testes - Epididymis - Vas deferens - Seminal Vesicle -Prostate Gland -> Urethra -> Penis → Ejaculated out of the Body
    • Disease: A particular distinctive process in the body with a specific cause and characteristics
      Disorder: Irregularity, disturbance, or interruption of normal Functions
    • Secondary dysmenorrhea
