Question: Answer the following question given this paragraph: Near the time of birth, the amniotic sac breaks in a gush of fluid. Labor usually begins within a day of this event. Labor involves contractions of the muscular walls of the uterus, which cause the cervix to dilate. With the mother's help, the contractions eventually push the fetus out of the uterus and through the vagina. Within seconds of birth, the umbilical cord is cut. Without this connection to the placenta, the baby cannot exchange gases, so carbon dioxide quickly builds up in the baby's blood. This stimulates the brain to trigger breathing, and the newborn takes its first breath. Q: During labor, what do contractions of the muscular walls of the uterus cause? A:
OPTIONS:
- spontaneous abortion
- excretion
- premature birth
- cervical dilation
Answer: cervical dilation
