Definition: birth from The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide

Act of producing live young from within the body of female animals. Both viviparous and ovoviviparous animals give birth to young. In viviparous animals, embryos obtain nourishment from the mother via a placenta or other means.

In ovoviviparous animals, fertilized eggs develop and hatch in the oviduct of the mother and gain little or no nourishment from maternal tissues. See also pregnancy.

The effectiveness of uterine contractions in this stage is enhanced by the bearing-down abdominal contractions of the mother.
