What does deglutition refer to?

Deglutition refers specifically to the act of swallowing, which is the process that allows food and liquids to move from the mouth into the esophagus and then into the stomach. This complex action involves multiple muscle movements and coordination and is an essential function in the digestive system.

Understanding deglutition is important in medical contexts, as difficulties in swallowing can lead to various health issues, including aspiration and nutritional problems. Among the other choices, the breathing process, circulation of blood, and digestion of food are related to different physiological functions, but they do not encompass the specific action of swallowing that deglutition describes.
