Final answer:
Effacement is not the opening of the cervix during birth.
Step-by-step explanation:
The statement that effacement is the opening of the cervix that occurs during the birth process is false.
Effacement refers to the thinning of the cervix during labor, not the opening. The term dilation is used to describe the opening of the cervix.
During stage one of labor, the cervix thins and dilates to about 10 cm. During stage two, the baby is expelled from the uterus. The last stage is the passage of the placenta after the baby has been born.
