Detailed explanation-1: -The pharynx is the region that connects the oral and nasal cavity to the esophagus and the windpipe. A cartilaginous flap called the epiglottis blocks food from entering the windpipe in the pharynx. The esophagus is a narrow and relatively long cylindrical structure that connects the pharynx to the stomach.

Detailed explanation-2: -It includes the lips, the lining inside the cheeks and lips, the front two thirds of the tongue, the upper and lower gums, the floor of the mouth under the tongue, the bony roof of the mouth, and the small area behind the wisdom teeth.

Detailed explanation-3: -The pharynx anatomy includes: Nasopharynx: The top part of the throat connects to the nasal cavities (nose) and lets air pass through. Oropharynx: The middle part of the throat connects to the oral cavity (mouth). It allows air, food and fluid to pass through.

Detailed explanation-4: -The oral cavity contains the teeth and tongue and receives the secretions from the salivary glands.

Detailed explanation-5: -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).
