Internal Anatomy • Ovaries • Fallopian tubes • Uterus • Vagina
Ovaries • Small paired oval-shaped glands located on either side of uterus • Produce eggs and hormones
Each ovary is enclosed in a tough protective capule and contains many follicles A follicle consists of 1 egg cell surrounded by 1 or more layers of follicle cells which nourish and protect the developing egg.
Most of 400,000 follicles are formed during fetal development * • Only several hundred follicles will release egg cells during a woman’s reproductive years
Fallopian tubes • Also called oviducts • Natrrow tubes that are attached to upper part of uterus • Serve as tunnels for ova (egg cell) to travel from ovaries to uterus
Uterus • Commonly called ‘womb’ • Pear-shaped muscular organ that is home to developing fetus • Divided into two parts • corpus- main part that expands to hold developing baby • cervix- lower part that opens into vagina and allows passage of sperm and menstrual blood
Vagina • Canal that joins cervix to outside of body • Commonly known as ‘birth canal’
External anatomy Vulva • Collective term for external genitalia • Houses vaginal opening and urethral opening (passing of urine) • Consists of pair of skin folds called labia minora and majora • Clitoris- tissue that plays a role in sexual arousal • Bartholin’s gland- secretes mucus that lubricates vaginal opening
Mammary Glands • Present in both sexes but normally function only in females • Not really part of female reproductive system but are important for sustaining young after birth • Small sacs of epithelial tissue that secrete milk which drains into a series of ducts that open into the nipple. • Fatty tissue (adipose tissue) forms mass of mammary glands of non-lactating mammals
