CAVITY OF THE BODY OF THE UTERUS

The 'Cavity of the Body' in the uterus is a mere slit, flattened antero-posteriorly.
It is triangular in shape, the base being formed by the internal surface of the fundus between the orifices of the uterine tubes, the apex by the internal orifice of the uterus through which the cavity of the body communicates with the canal of the cervix.
