Labor happens in four stages:
- First stage: Dilation of the cervix (mouth of the uterus)
- Second stage: Delivery of the baby.
- Third stage: Afterbirth where you push out the placenta.
- Fourth stage: Recovery.

There are three stages to the birthing process, or parturition: dilation of the cervix, delivery of the calf and delivery of the placenta. Knowing the normal birth process will help you decide whether or not to intervene.
What are the phases of uterine contraction?

What are the 3 phases of the first stage of labor?
The first stage of labour begins with contractions that continue to increase in length and intensity, and ends when the cervix is fully dilated. This can last anywhere from a few hours to a few days. It has three phases: early, active and transition.

Which of the following is the first step in the parturition process?
The first stage of parturition is dilation of the cervix. The normal cervix is tightly closed right up until the cervical plug is completely dissolved. In stage 1, cervical dilation begins some 4 to 24 hours before the completion of parturition.
What is uterine contraction?
Uterine contraction: The tightening and shortening of the uterine muscles. During labor, contractions accomplish two things: (1) they cause the cervix to thin and dilate (open); and (2) they help the baby to descend into the birth canal.
What are the 7 cardinal movements of labor?
Anglo-American literature lists 7 cardinal movements, namely engagement, descent, flexion, internal rotation, extension, external rotation, and expulsion.
What happens during the 3rd stage of labor?
In the third stage of labour the uterus contracts, and the placenta completes its separation from the wall of the uterus and is birthed. This stage can take five to 30 minutes or longer. During this time you may experience cramps and be asked to push out the placenta.
What are the first stages of labor?
The cervix must be 100 percent effaced and 10 centimeters dilated before a vaginal delivery. The first stage of labor and birth occurs when you begin to feel regular contractions, which cause the cervix to open (dilate) and soften, shorten and thin (effacement). This allows the baby to move into the birth canal.
What is parturition which hormones are involved in parturition?
Parturition is the end point of a succession of endocrine events involving maternal, fetal and placental interactions. The major hormones involved in the onset and maintenance of human parturition are oestrogens, progesterone, relaxin, oxytocin, prostaglandins, catecholamines, cortisol and β-endorphin.
What are the different stages of parturition?
1 Dilation Dilation defined as the uterus begins to enlarge and rupture the membranes. It also starts a bloody discharge progressively. 2 Expulsion This second stage of parturition starts at full dilation and continues until birth. 3 Placental
