Female Reproductive Anatomy
K.Matthews
What is the function of the female reproductive system?
• Produce Eggs• Deliver eggs to the site where fertilization by
the male can occur• Provide an environment for the growth and
development of the embryo• Expels the fetus when it is capable of survival
on its own
What are the components?
• 2 Ovaries• 2 Uterine Tubes (oviducts)• Uterus– Body– Cervix– 2 horns
• Vagina• Vulva
Ovaries
• Primary organs of reproduction in females• Produce hormones and eggs– Estrogen and Progestins
• Oval shaped in most animals but kidney bean-shaped in the mare
Ovaries
Ovaries
Oviducts (uterine tubes)
• Paired, convoluted tubes, lined with cilia• Egg travels down oviduct from ovary to
uterine horn• In most species fertilization occurs in the
oviduct• Has funnel shaped end called infundibulum
which partly surrounds each ovary and catches the egg when it’s released
Oviducts
Oviducts
Uterus
• Consists of body, two uterine horns, cervix– Vary in size, shape, proportions, and arrangement
in different species
• Body of the uterus is largest in the mare
Uterus
Uterus
Cervix
• Projects into vagina• Heavy smooth muscle sphincter• Site of semen deposit in sows and mares• Closed except during estrus– Prevents microbial contamination of uterus
Cervix
Vagina
• Birth Canal• Organ of copulation• Site of semen deposit during natural mating in
cows, does, ewes
Vagina
Vulva
• External opening to the reproductive tract• Indicates the mare is in heat and ready to be
bred– Swelling– Discharge– Winking
