1. Female Reproductive Tract
Original Power Point Created by Linda Rist

2. Broad Ligament
suspends the female reproductive tract in the pelvic cavity
has three portions

3. Ovary
release ova- egg
50, ,000 potential eggs present at birth
release hormones
progesterone
estrogen

4. Oviduct
(fallopian tube)
connect ovary to uterine horns

5. Oviduct
three portions
infundibulum
ampulla
isthmus

6. Oviduct ova remains in oviduct for 3-6 days 1/8 inch in diameter
20 cm. Long in a cow

7. Uterus passageway for sperm cells from cervix to oviduct
produce histotroph - nourishes developing embryo until placenta forms
expel fetus at parturition

8. Parturition
birth

9. Uterus
site of pregnancy

10. Cervix located between uterus and vagina
forms a barrier between the internal and external environment
thick walled, many ringed organ

11. Vagina point where urinary and reproductive tracts join
receptacle for semen
passageway for fetus

12. Vulva
outer opening of reproductive tract

13. Clitoris
sensory organ

14. Hormones
estrogen
progesterone
FSH LH
HCG

15. Estrogen
produced by the follicle in non pregnant female and placenta in late pregnancy
induce estrus - heat
responsible for female contour

16. Estrogen develop duct system of mammary gland
causes edema - retention of water
increases muscle development

17. Progesterone hormone that keeps female out of heat relaxes uterus
secretion of histotroph

18. FSH follicle stimulating hormone development of follicles on ovary
ova are released from follicle

19. FSH
indirectly responsible for estrogen production

20. LH Lutenizing hormone causes ovulation
ova is released from the follicle

21. HCG Human Chorionic Gonadotropin
produced by the placenta of pregnant women early in pregnancy

22. HCG
used on cows that are cystic - won’t ovulate
causes ovulation

23. Ovulation release of ova from ovary
follicle develops - blister on ovary
follicle bursts - egg is released

24. Ovulation a hole is left where the ova was
forms a C.L. (Corpus Luteum) - yellow body

25. C.L. produces progesterone
if female becomes pregnant a new follicle does not burst and estrogen production is reduced

26. Gestation length of time from conception till birth cows - 281 days
pigs days (3 mos, 3 weeks, 3 days)
horses days

27. Gestation
sheep days
goats days
