"Phagus" is not a known term or concept in mainstream Biology or any scientific field. It might be a misspelling or a made-up term. Can you provide more context or clarify your question so that I can give a more accurate response?
You might mean the esophagus. That is the tube between the throat and the stomach. The root phag+ means swallow or eat, and the phagus is the flap that pushes food down when you swallow. The prefix "eso-" means "out from," so the esophagus leads out from the phagus.

The word is properly transliterated as oesophagus (Greek: οισοφάγος). It is composed of two words: oeson (meaning cord, rope or tube) and phagus (meaning to eat). So basically, the meaning of the word is "food tube", i.e. the tube via which the food descends from the mouth to the stomach.
