Define the parturition in animal

Parturition, also known as childbirth or delivery, is the process by which a pregnant animal gives birth to its offspring. This process typically involves the expulsion of the fetus(es) from the mother's uterus through the birth canal. During parturition, hormonal changes and uterine contractions help to facilitate the passage of the offspring out of the mother's body. Parturition is a natural and essential process for the continuation of a species.
