It can be confusing to know the different parts of the body. Some parts of the body are not being discussed as much such as the uvula and the epiglottis. When you say epiglottis, this can be found near the larynx. The uvula, on the other hand, can be found at the base of the tongue. Their functions are also different from each other. The uvula will be in charge of helping you produce the sound that you need.
The epiglottis, on the other hand, will be in charge of making sure that food and other liquid will not enter the trachea when people are swallowing. When this happens, a person might have food and drinks enter the nasal cavity.
