Detailed explanation-1: -The epiglottis is usually upright at rest allowing air to pass into the larynx and lungs. When a person swallows the epiglottis folds backward to cover the entrance of the larynx so food and liquid do not enter the windpipe and lungs. After swallowing the epiglottis returns to its original upright position.
Detailed explanation-2: -Aspiration is when something enters the airway or lungs by accident. It may be food, liquid, or some other material. This can cause serious health problems, such as pneumonia. Aspiration can happen when a person has trouble swallowing normally. This is known as dysphagia.
Detailed explanation-3: -Your trachea’s main function is to carry air in and out of your lungs. Because it’s a stiff, flexible tube, it provides a reliable pathway for oxygen to enter your body.
