Life Health Sciences – Science Rules it All

A pairs of ovaries are the reproductive organs in woman. They are present just below the kidneys in the abdominal cavity. Each ovary has several sac like structures called OVARIAN FOLLICLES of GRAFFIAN FOLLICLES. Each follicle has a centrally placed cell called OVUM. The ovum is formed from a cell called PRIMARY OOCYTE. When ovum matures, the follicle ruptures and releases the ovum. Every time, only one follicle ruptures and releases one ovum into body cavity. The ruptured follicle is called CORPUS LUTEM and it secretes female sex hormones – oestrogen and progesterone. FSH (Follicle Stimulating Hormone) secreted by pituitary stimulates the growth of follicle and luteinizing Hormone (LH) secreted by pituitary stimulates the rupture of follicle and conversion of follicle into corpus luteum.

The ovum released from the follicle enters into a tube called FALLOPIAN TUBE. The anterior end of this tube is like a funnel, with several finger like structures and is also ciliated. The movement of cilia helps in movement of ovum through the fallopian tubes into UTERUS. This is a sac which opens into another muscular tube called VAGINA.
