The uterus is part of the female internal genitals: the place where a fertilized egg is embedded and grows into a child.
This muscular organ is pear shaped, 7-10 cm long (3 inches) and 5 cm wide (2 inches).
The uterus is held in place by six ligaments and the position of the uterus varies from girl to girl, in 25% it is tipped backward and in 10% it is tipped forward.
The inside of the uterus is not hollow, the sides touching one another. Like the vagina it is not actual, but potential space. The lining is richly supplied with glands and blood vessels.
At the bottom the cervix connects the uterus with the vagina, with the cervix protruding into the vagina. At the top the uterus is connected with the fallopian tubes, where fertilization takes place.
Its main function is to receive and feed the fertilized egg cell.
