What are the three stages of labor?

The three stages of labor are accurately described as dilation, expulsion, and placental stage.

During the dilation stage, which is the initial phase of labor, the cervix opens (dilates) to allow the baby to move into the birth canal. This stage can last several hours, especially for first-time mothers, and involves regular contractions that become progressively stronger and closer together.

The expulsion stage follows, where the mother pushes and exerts effort to deliver the baby. This stage often involves significant physical labor for the mother, and it concludes with the birth of the baby.

Finally, the placental stage occurs after the baby is born. In this stage, the placenta, which has provided nutrients and support to the developing fetus, detaches from the uterine wall and is expelled from the mother's body. This is a crucial step to ensure that the uterus returns to its non-pregnant state and minimizes the risk of complications.

Therefore, the stages delineated in the correct answer encapsulate the process of childbirth in a straightforward manner, highlighting the key transitions that occur during labor.
