During which stage of labor does the cervix dilate to 10 centimeters?

The first stage of labor is characterized by the gradual dilation of the cervix up to 10 centimeters, which is essential for the baby to move down the birth canal and be delivered. This stage is divided into three phases: the latent phase, active phase, and transition phase, all contributing to the overall cervical dilation. The process begins with mild contractions that become progressively stronger and more frequent, leading to full dilation.

The second stage of labor begins once the cervix is fully dilated to 10 centimeters and involves the pushing phase, where the mother exerts effort to help the baby descend and be born. The third stage of labor occurs after the baby is delivered and involves the expulsion of the placenta. The latent phase is part of the first stage of labor and does not encompass the full dilation process. Therefore, the correct answer accurately reflects the stage where cervical dilation occurs up to the required 10 centimeters for childbirth.
