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
When you swallow, a small flap of tissue called the epiglottis covers the opening to the windpipe (trachea), directing food down the esophagus into the stomach. This process is coordinated by the swallowing reflex, preventing food from entering the windpipe and causing choking.
