Parturition

Answer 1

Parturition-

1. Childbirth in viviparous mammals is called parturition.
2. It is the process of the contraction of the uterus at regular intervals that helps in the delivery of the baby at the end of pregnancy.
3. During the parturition process, the cervix dilates and relaxes. Along with cortisol, oxytocin and estrogen hormones are released to begin milk production and labor.
4. During parturition, the uterus contracts to push the fetus towards the cervix and continues until the fetus comes down the birth canal. In this process, the head should be the first to come out.
5. After parturition, the uterus releases the placenta and it passes out immediately after the fetus is born.
6. Lactation begins and the first milk is called colostrum.
7. This milk contains antibodies, which are required for a newborn baby to protect it against infectious diseases and other allergies.
