PATHOLOGY

Detailed explanation-1: -Swelling of the epiglottis can completely block the airway. This can lead to breathing or respiratory failure. In this life-threatening condition, the level of oxygen in the blood drops very low.

Detailed explanation-2: -The most common cause is bacterial infection. Epiglottitis symptoms include pain when swallowing, severe sore throat and difficulty breathing. Epiglottitis is a medical emergency. It’s important to seek treatment immediately if you develop symptoms.

Detailed explanation-3: -If the epiglottis is absent in the body then the regulation of food material to esophagus and air into the lungs will get disturbed. Sometimes food will enter into the windpipe and then causes choking. Eventually, the lungs cannot not work properly which can lead to death.

Detailed explanation-4: -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.
