Reproductive System Annabel Quintero (Disorders (down syndrome,…

- - - - Follicular cells secrete estrogen to become secondary follicle
      - extends from the beginning of menstruation until ovulation
      - FSH causes follicular cells develop into primary follicle
    - - triggered by sudden spike increase in LH caused by steady increase in estrogen stimulating the pituitary gland
      - graafian follicle releases the oocyte
      - slight rise in progesterone just before ovulation causes basal body temperature to rise about 0.4-0.6 degrees
    - - follicle expels the oocyte, the empty shell becomes corpus luteum
      - corpus luteum secretes progesterone, some estrogen, and inhibin which suppresses FSH
  - - - decline of estrogen and progesterone cause the spiral arteries to constrict, cells become ischemic and die, and are sloughed off or shed (through bleeding)
      - bleeding last for 3-5 days
    - - estrogen stimulates growth of blood vessels of the endometrium, causing it to double in thickness
      - thickening of endometrium allows ovulated egg to be caught to cause implantation
      - uterus is preparing for fertilized egg
    - - in response to rising levels of progesterone by the corpus luteum, the uterus becomes ready for pregnancy
      - uterine glands enlarge and secrete nutrients to sustain the embryo until implantation occurs
      - if pregnancy does not occur, towards the end of phase, LH levels drop due to high levels of progesterone
- - - - function as sperm-producing factories
    - - functions to mature and store sperm cells
    - - carries the sperm from the epididymis to the ejaculatory duct
    - - carries both sperm and urine
    - - Carries both sperm and urine helps activate sperm
    - - secrete an alkaline mucus in response to sexual stimulation, and lubricates penis for penetration just before ejaculation
    - - regulates temperature of testes for sperm viability
    - - delivers semen into female reproductive tract
  - - - receive the ovulated oocyte and provide a site for fertilization
    - - receive a fertilized egg, retain the fertilized egg, and nourishes the fertilized egg
    - - serves as birth canal
    - - fatty pad over the pubic symphysis, covered by pubic hair after puberty
    - - skin folds around the vaginal opening
    - - contains the opening to the urethra and greater vestibular gland or Bartholin’s gland (produce mucus)
    - - corresponds to the male penis
    - - produce milk (lactation)
