The suffix "-phagia" is most closely related to which of these functions?

The suffix "-phagia" is derived from Greek, where it signifies eating or swallowing. This term is commonly used in medical terminology to refer to various conditions or actions associated with the intake of food. For example, "dysphagia" denotes difficulty in swallowing, highlighting the connection between the suffix and the swallowing function.

In this context, linking "-phagia" primarily to the act of swallowing is essential for understanding how it is used in medical language. The other options do not share this direct relationship with the suffix, as they represent different actions or states that do not pertain to the process of taking in food or substances through the mouth and into the digestive tract.
