• It can be divided into three parts – fundus, body and cervix.
• The fundus is upper, the dome-shaped part above the opening of the fallopian tube. 
• The middle and major part of the uterus is the body. It has three layers – outer peritoneal perimetrium, middle muscular myometrium and highly vascular endometrium. 
• The lower narrow part which opens in the body of the uterus by internal os and in the vagina by external os is called the cervix.
• The uterus is the site of foetal placentation, its growth and parturition.

Vagina:
