Answer: D - The top of the growing uterus is called the fundus, and the healthcare provider will measure from the fundus to the pubic bone as pregnancy progresses. This measurement in centimeters is used as a gauge of the fetal growth compared to norms for the week of pregnancy in which the measurement is taken. Os is another word for opening, and the cervix is actually the os of the uterus. The cervix is filled with a mucous plug during pregnancy to prevent anything from entering the interior. The placenta is attached to the interior of the uterus, and provides all the nutrients and oxygen to the baby via the umbilical cord.
