Cervix - GCSE Biology Definition
Reviewed by: Lára Marie McIvor

The cervix is a part of the female reproductive system and is the lower, narrow end of the uterus (womb) that connects to the vagina. It acts like a gateway, allowing menstrual blood to leave the body and sperm to enter the uterus during reproduction. The cervix also plays a crucial role during childbirth, as it stretches and opens to let the baby pass through. It produces mucus that changes in thickness throughout the menstrual cycle, which can help or prevent sperm from entering the uterus. Understanding the cervix is important when studying the process of reproduction and how the female body prepares for pregnancy.
