The cervical canal is the passageway through the cervix, connecting the uterus to the vagina. It allows sperm to enter the uterus and menstrual blood to exit. During childbirth, it widens to allow the baby to pass through. Think of it as the gatekeeper of the uterus. Mucus in the cervical canal changes throughout the menstrual cycle. It plays a crucial role in both fertility and childbirth.
