Final answer:
Childbirth education classes aim to increase the knowledge of expectant parents about labor and delivery, including stages of labor, hormonal changes, and possible interventions.
Step-by-step explanation:
The goal for the couple who attends childbirth education classes is primarily to increase knowledge of labor and delivery. During childbirth education classes, couples learn about the different stages of labor, which include the dilation of the cervix, the expulsion of the baby, and the delivery of the placenta. They are also informed about the hormones that play a role in pregnancy and labor, such as estrogen, progesterone, and hCG, as well as potential interventions like synthetic oxytocin. Classes can cover various aspects of childbirth and postpartum care, helping expectant parents to make informed decisions and prepare for the arrival of their child.
