What term describes the lower part of the uterus?

The term that describes the lower part of the uterus is the cervix. The cervix serves as the passageway between the vagina and the uterus, and it plays a critical role in reproductive health, particularly during childbirth and menstruation. It acts as a barrier to protect the uterus from infections and is important during pregnancy as it keeps the fetus in the uterus.

The fundus, which is another part of the uterus, refers to the top portion above the openings of the fallopian tubes. The body of the uterus refers to the main central part, and the endometrium is the inner lining of the uterus that thickens during the menstrual cycle and sheds if pregnancy does not occur. Understanding these terms and their functions is crucial for anyone studying health sciences, as it relates to anatomy and reproductive health.
