What is the role of the cervix?

Secreting mucus, giving birth to a fetus. The cervix is a part of the uterus, which can play a certain role in preventing and blocking premature birth and abortion. The cervix secretes a certain amount of alkaline mucus, which has a certain preventive effect on the invasion of bacteria and other pathogens.

The cervix is related to the prevention and treatment of diseases and health care such as gynecology, obstetrics, family planning, women's health and reproductive health in a woman's life. Health care in this area is needed.
