List and describe the stages of childbirth.

Childbirth, also known as labor and delivery, is typically divided into three stages:

1. Stage 1: Early Labor and Active Labor
During early labor, the cervix begins to dilate and contractions become more regular and intense. This stage can last for several hours and is often characterized by the onset of mild to moderate contractions. As labor progresses into active labor, the contractions become stronger and more frequent, and the cervix continues to dilate. This stage can last anywhere from a few hours to a day or more.

2. Stage 2: Delivery of the Baby
Once the cervix is fully dilated, the second stage of labor begins. This is when the baby is pushed through the birth canal and delivered. Contractions during this stage are intense and frequent, and the mother will actively push with each contraction to help move the baby through the birth canal. This stage can last anywhere from a few minutes to a few hours, depending on various factors such as the position of the baby and the mother's pushing efforts.

3. Stage 3: Delivery of the Placenta
After the baby is born, the third stage of labor involves the delivery of the placenta. This stage typically lasts only a few minutes and is much less intense than the previous stages. The uterus continues to contract, causing the placenta to separate from the uterine wall and be expelled from the body.

It's important to note that every childbirth experience is unique, and the duration and intensity of each stage can vary from person to person. Additionally, complications or medical interventions may alter the typical progression of labor and delivery. It's always best to consult with a healthcare provider for personalized information and guidance on the stages of childbirth.
