FEMALE REPRODUCTION SYSTEM 2 The female reproductive system includes: 1 . ovaries , which produce secondary oocytes (cells that develop into mature ova only after fertilization) and several hormones 2 . uterine (fallopian) tubes or oviducts , which transport secondary oocytes and fertilized ova to the uterus 3.the uterus , in which embryonic and fetal development occur 4. the vagina , which leads from the exterior to the uterus 5 . the vulva or pudendum , the external genital organs 6. mammary glands , which produce milk.

Ovaries 3 The ovaries are homologous to the testes. The ovaries are paired glands, located in the pelvic cavity, one on each side of the uterus. Each ovary is held in position by a series of ligaments: i. The broad ligament of the uterus which is a fold of the peritoneum, attaches to the ovaries by a subset of this peritoneal fold called the mesovarium . ii. The ovarian ligament anchors each ovary to the uterus. iii. The suspensory ligament attaches each ovary to the pelvic wall.

Uterine (fallopian) tubes or oviducts 4 The two uterine tubes extend laterally from the uterus and transport secondary oocytes and fertilized ova from the ovaries to the uterus. Narrow, 4-inch (10cm)tube extends from ovary to uterus 1. The infundibulum is open, funnel-shaped lateral portion of each tube and is located close to the ovary. The end of the infundibulum is encircled by a fingerlike fimbriae . The medial end of the uterine tube attaches to the superior lateral angle of the uterus. 2. The ampulla is the lateral two-thirds ,which is the widest, longest portion. 3. The isthmus , is the medial portion which is the short, narrow, thick-walled portion that joins the uterus.

Uterine or Fallopian Tubes 5 After ovulation and the entry of the secondary oocyte into the uterine tube (due to currents created by the motile fimbriae), fertilization (if it occurs) typically occurs in the ampulla , resulting in the formation of a zygote; after several cell divisions, the early embryo typically arrives at the uterus about 6–7 days after ovulation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
