Which anatomy term refers to the lower part of the uterus that opens into the vagina?

Explanation:
The term is the cervix. The cervix is the lower, narrow portion of the uterus that connects to the vaginal canal, acting as a gate between the uterus and vagina. It stays closed most of the time and only opens during menstruation, fertilization, and childbirth, allowing passage when needed. It also produces mucus that changes during the menstrual cycle, which can affect sperm movement. The other terms refer to different parts: the vagina is the external canal that leads to the cervix; the uterus is the whole hollow organ; and the endometrium is the inner lining of the uterus that thickens and sheds each cycle.
