What is the process called when animals use oxygen to release energy from food? (respiration)

How do mammals give birth to their young? (live birth)

Mammals give birth to their young through live birth, a process in which the offspring develop inside the mother's body and are born fully formed. During gestation, the developing offspring receive nourishment and oxygen through the placenta, a structure that connects the developing fetus to the mother's circulatory system. When the offspring are fully developed, the mother goes into labor, and contractions of the uterus push the offspring out through the birth canal. This process allows mammals to give birth to live, fully developed young rather than laying eggs like other animals.
