How can we breathe and eat at the same time?

In breathing, air may flow through either the nose or the mouth, it always flows through the pharynx. During swallowing, the pharynx changes from an airway to a food channel. The pharynx is isolated from the nasal cavity and lower airway by velopharyngeal and laryngeal closure during the pharyngeal swallow.

Why do we breathe and eat through the same hole?

For example, we eat and breathe through the same hole, which is a choking risk. That’s why we have an epiglottis (the thing that closes when we swallow so food doesn’t go into our trachea). The epiglottis was an adaptation to improve on an imperfect system. We breathe through nose and eat and drink via mouth.

Does food and drink go down the same hole?

Our breathing tube, the windpipe or trachea, isn’t segregated from the one we use for swallowing, the esophagus. Air, food, and drink all share the same commute down the throat until the trachea branches off, right around your Adam’s apple. Normally, the epiglottis keeps food and drink from going down the windpipe.

How do dolphins eat underwater?

Marine mammals feed entirely underwater. Seals and dolphins can hunt, catch, and swallow food beneath the water. Marine mammals make sure that they capture their prey and not swim away before swallowing. They do this by sucking the food deeper into the mouth by pulling back their tongue once the prey is in their mouth.
