The process of giving birth to new ones is known as reproduction. Unicellular creatures reproduce their offspring through cell division. Some lay eggs and some give birth to baby. Females becomes pregnant due to fertilization of sperm and ovum after fertilization. The foetus developed in uterus and it takes birth after some specific time.
The ovaries are of oval shapes. They are 2.5 to 3.5 cm long, 2cm wide and 1 cm thick. They lie in the pelvis, one on either side of the uterus and each is anchored to the uterus by an ovarian ligament. They secret the hormones responsible for female development and produce the ova.
The vagina is about 10 cm long fibro elastic muscular tube which connects the uterus with the external reproductive organ (vulva). It is composed of mucus and fibroblastic connective tissues lying behind the urethra and bladder and in front of the rectum. Its main function is to receive the penis during intercourse and allows menstrual flow and passage for the baby to the outside world.
Uterus is a pear like organ lies between the bladder and rectum. The fertilized ovum becomes implanted, receives nourishment and develops over a period of 9 months in this organ. There are 3 parts in this organ. They are: fundus, body and cervix.
