Respiration is the biological process that results in the gradual release of energy. The food (glucose) is metabolized into CO2 and water during respiration.
Below the tongue is the epiglottis, a leaf-shaped flap-like cartilage structure. During eating, this flap stops the windpipe from inhaling food.
The epiglottis is a tube that permits air to enter the larynx. When food is swallowed, the epiglottis closes the laryngeal aperture, preventing food from entering the food pipe.
The dome-shaped muscle that separates the chest from the abdomen is known as the diaphragm.
The diaphragm flattens and contracts during inspiration. Air is drawn into the lungs by this contraction. The diaphragm relaxes during expiration.
The lungs are drained of air as a result of this relaxation.
Final Answer:
During respiration, the epiglottis prevents food from being inhaled, and the diaphragm aids in the processes of inspiration and expiration.
