Detailed explanation-1: -Oropharynx: Food and air pass through the oropharynx together. This channel is used for food, drink, and air. Even though air enters through the nasal cavity and food, and water enters through the oral cavity, the two passages unite at a point to form the structure – the oropharynx.

Detailed explanation-2: -Air, food and liquid all pass through this common passage, the oropharynx. The two passages separate again here, in the hypopharynx. Food and liquid pass backward into the esophagus on their way to the stomach. Air passes forward through the larynx and into the trachea, on its way to the lungs.

Detailed explanation-3: -The pharynx, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.

Detailed explanation-4: -What is the throat? The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
