Final answer:
The cervix is the neck-like region of the womb that protrudes into the vagina and connects the uterus and vagina. It plays a crucial role in childbirth.
Step-by-step explanation:
The unscrambled word is cervix, which refers to the neck-like region of the womb.
The cervix is the lower part of the uterus and it protrudes down into the vagina. It acts as a passageway between the uterus and the vagina and also plays a role in childbirth.
For example, during labor, the cervix dilates or opens up to allow the baby to pass through from the uterus into the birth canal.
