  8. Female Reproductive System

  9. Female Reproductive System • Bartholin’s Gland: • Secretes mucus to lubricate the vagina • Cervix: • Connects the uterus to the vagina • Fallopian Tube: • 4 inch tube that connects the ovary to the uterus. • Labia Major: • Heavy skin folds that surround the opening of the vagina

  10. Female Reproductive System • Labia Minor: • Two smaller folds of skin located within the labia major • Ovary: • Female reproductive glands that produce ovum (eggs) and estrogen • Uterus: • It is within the uterus that the fetus develops during gestation • Vagina: • Muscular tube that connects the uterus to the outside of the body. Serves for sexual intercourse, the birth canal, and the passage way for menstrual flow.

The Menstrual Cycle • Days 1-5 • The menstrual flow leaves the body (2 ounces of blood and uterine lining) • Days 6-12 • Uterine lining rebuilds itself in thickness • Days 13-14 • Ovulation occurs: an egg is released into the fallopian tube • Days 15-20 • Corpus luteum (temporary gland) secretes hormones (estrogen and progesterone) to support pregnancy • Days 21-28 • Corpus luteum disintegrates if egg is not fertilized

  18. At the beginning of the menstrual cycle the pituitary gland releases the hormones LH and FSH. • FSH acts on the ovaries • Causes egg to mature and follicle in ovary to produce more estrogen
