The uterus is part of a woman's reproductive system. It's the organ that contains the growing fetus.
The cervix forms the neck of the uterus, and the vagina is the canal through which conception and birth take place. The endometrium is a soft lining that protects the fetus during pregnancy.
Reasons for having a D and C vary. Most D and C's are performed because the patient has complained of unusually heavy menstrual bleeding.
Other common problems include, uterine infection, bleeding after sexual intercourse, incomplete miscarriage or the presence of polyps - small pieces of extra tissue growing on the inside of the uterine wall.
