Answer 2

Common passage for food and air is the OROPHARYNX. Air, food and liquid all pass through this passage.

Even though the passage of food and water and the passage of air are separated at the beginning i.e. air enters through nasal cavity and water and food enters through oral cavity. Then, the two passages unite to form oropharynx.

Further the two passages again gets separated i.e. food and water enters the esophagus and the air enters the trachea.
