Step-by-step explanation:
The dome-shaped superior portion of the uterus is called the fundus. The fundus is located above the opening of the uterine tubes and is part of the uterus which nourishes and supports a growing embryo. The uterus is commonly described as having three sections: the fundus, the body (also known as the corpus), and the cervix, which is the narrow inferior portion that projects into the vagina. The cervix has several functions, including producing mucus secretions that facilitate sperm movement and acting as a passageway during childbirth.
