THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Your cervix needs to open about 10cm for your baby to pass through it. This is what’s called being fully dilated. In a 1st labour, the time from the start of established labour to being fully dilated is usually 8 to 12 hours. It’s often quicker (around 5 hours), in a 2nd or 3rd pregnancy.

Detailed explanation-2: -Active labor. During active labor, your cervix will dilate from 6 centimeters (cm) to 10 cm. Your contractions will become stronger, closer together and regular.

Detailed explanation-3: -The second stage of labor starts after your cervix has dilated (opened) to 10 centimeters (about 4 inches), and it continues until your baby finishes moving through your vagina and is born. During this time, you will push or bear down (like you do when you have a bowel movement) to help your baby come out.

Detailed explanation-4: -During the active stage of labor, your cervix dilates from around 6 cm to the full 10 cm. (The last part of active labor, when the cervix dilates fully from 8 to 10 cm, is called transition.) This process takes about 5 to 7 hours if you’re a first-time mom, or between 2 and 4 hours if you’ve had a baby before.
