Air beginning the body with the sleep or mouth, i beg your pardon are associated through the nasal and oral cavities to the pharynx, with which air overcome to the larynx and food to the esophagus. Air passes with the larynx (the voicebox), and also then to the trachea, the "windpipe". The main brochial passageways (bronchi) subdivide in the lungs right into smaller and smaller airways, and also finally to the separation, personal, instance air sacs called alveoli, wherein oxygen enters the bloodstream.
You are watching: What structure prevents food from entering the windpipe
Ethmoid bone,The superior part of the sleep is sustained by the nasal, frontal, and also maxillary bones; the inferior part includes number of cartilages. The continuous free margin of the sleep bones and also maxillae in a dried skull is termed the piriform aperture.
The epiglottis moves back and soon to protect against the passage of food and also liquids right into the lungs. The normal upright place of the epiglottis allows air to flow into the lungs and also the larynx.

he throat (see the picture below) is component of both the digestive and also respiratory systems and is responsible for coordinating the functions of breathing and also swallowing. From premium to inferior, the throat is subdivided into 3 sections: oropharynx, hypopharynx, and also larynx. Together, the oropharynx, hypopharynx, and also larynx duty to sense and propel a food bolus native the mouth come the stomach in a coordinated fashion while protecting the airway.
