Simple uterus Unusual placenta arrangement Inefficient cervical closure Small uterine body Two long, narrow uterine horns Suspended in abdominal cavity by ligaments and connective tissue to the abdominal wall Uterus • Consists of a body, cervix, and two horns • Elongated shape causes a lot of infection because it can’t drain efficiently • Falls lower and lower with each pregnancy Fallopian Tubes (oviducts) • Site of fertilization • Connect ovary and uterus Ovaries • Secrete the hormone estrogen • Produces eggs or ova in the female Fertilization: • Sperm unites with the egg and produces a zygote Cervix: • Seals to prevent bacteria from entering • The closure of the seal is vital to embryo survival • The closure is controlled by hormonal levels and can be unstable • Possible cause of early embryonic death Placenta: • Attached to the endometrial lining of the uterus by tons of tiny villi • Transfers blood, oxygen, and nutrition to the baby Vagina: • Receives the sperm during mating • Passageway during parturition (birth)
