Young woman drinking with a straw.

Infants, and all baby mammals, are born with a sucking (or suckling) reflex, which they use in nursing liquid foods, such as milk. They do not have to learn this reflex, because it is instinctive. Some adult animals use suction in drinking, as do humans when using drinking straws. In breathing, the diaphragm muscle is used to expand the lungs, allowing air to enter due to the outside air pressure.
