Final answer:
The correct answer is B.The upper section of the uterus is referred to as the fundus, which is located superior to the opening of the uterine tubes and plays a role.
Step-by-step explanation:
The upper section of the uterus is called the fundus. The uterus is a pear-shaped, muscular organ where a fetus grows and develops during pregnancy.
It is divided into three sections: the fundus, the body, and the cervix. The fundus is the portion of the uterus that is superior to the opening of the uterine tubes.
The middle section is referred to as the body of the uterus, also known as the corpus. The cervix is the narrow, inferior portion of the uterus that projects into the vagina.
It is important to note that the fundus plays a role in supporting the growing embryo, and during pregnancy, the uterus, including the fundus, can greatly expand to accommodate the developing baby.
