What causes swelling of the epiglottis?
Epiglottitis is usually caused by an infection from Haemophilus influenza type b (Hib) bacteria, the same bacteria that cause pneumonia and meningitis. Transmission of the bacteria is the same as with the common cold: Droplets of saliva or mucus are spread into the air when a carrier of the bacteria coughs or sneezes.
Is trachea covered by epiglottis?
It is thus the valve that diverts passage to either the trachea or the esophagus. The epiglottis is made of elastic cartilage covered with a mucous membrane, attached to the entrance of the larynx….

Is a swollen epiglottis bad?
Epiglottitis is characterized by inflammation and swelling of your epiglottis. It’s a potentially life-threatening illness.
What happens when the epiglottis does not function properly?
Normally, a flap called the epiglottis blocks food particles and stomach contents from entering your lungs. Dysphagia can disrupt this process. Aspiration is serious because it can lead to pneumonia and other problems. Problems with any of the phases of swallowing can cause dysphagia.
What is the role of the trachea in the respiratory system?
What does the trachea do? 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.
Can Covid cause a swollen epiglottis?
COVID-19 infection is well documented to cause upper respiratory tract symptoms, and as such we believe that in the absence of any other positive microbiological investigations, it is highly likely that COVID-19 was the aetiological cause of acute epiglottitis in this instance.
Can you swallow without an epiglottis?
We conclude that the epiglottis is not essential for successful swallowing in humans, because individuals can readily adapt to isolated epiglottectomy and avoid tracheal aspiration.
