Ovary: Each ovary contains immature ova (eggs) in follicles.
(ii) Females born with lifetime supply of eggs (250,000-400,000 in each ovary)
(iii) Ovaries release ovum -. Almost all ova degenerate between birth and puberty.
(iv) Approx. 400 eggs will be ovulated over woman'* life.
(v) Egg is the largest human cell.
(vi) Ovaries are located lower abdomen. 1 left and 1 on the right.
Fallopian tubes
(i) Two thin tubes attached to the upper sides of **
(ii) Tubes terminate near the ovaries but are not attached
(iii) "Fimbriae" are finger-like structures on the end of each tube
(iv) Tubes conduct egg to ** by use of small hairs called "cilia"
(v) Fertilization of ovum takes place in the ampullaryisthmic junction of the fallopian tubes. Egg viable for only 24-48 hours after ovulation.
Uterus:
(i) Pear-shaped organ located in lower abdomen.
(ii) Muscles(myometrium) stretch to allow baby to develop. Oxytocin starts labor contractions.
(iii) Lining of uterus (endometrium) thickens with blood-rich tissue due to progesterone.
(iv) Endometrium supports embryo/fetus during growth.
(v) Placenta :It is the interface between baby and mother. If not pregnant, lining breaks down and is discharged from body through **. This is menstruation (**).
(vi) Cervix connects **** to vagina**. Like a door that opens during ovulation. Cervical mucous closes the door at all other times.
