The esophagus and windpipe meet at a point called the pharynx, specifically at the laryngopharynx, which is the lower part of the pharynx located behind the larynx (voice box). The esophagus then continues down to the stomach, while the windpipe leads to the lungs.
No, they do not need any. The only valve that has anything to do with the lungs is at the top of the trachea (windpipe) and closes off the lungs when you swallow, it is called the epiglottis.
Windpipe
When you swallow, the larynx moves up slightly, and a flap called the epiglottis closes over the trachea.
The glottus
You cannot breathe and swallow at the same time because of the anatomy of the throat. When you swallow, the epiglottis closes over the trachea (the windpipe) to prevent food or liquid from entering the airway, directing it instead to the esophagus. This protective mechanism temporarily halts breathing to ensure that the airway remains clear, which is crucial for preventing choking and aspiration. Therefore, the body prioritizes swallowing over breathing during this action.
