Final answer:
Dysphagia is the term for difficulty swallowing, which can interfere with the complex process of deglutition, involving several phases and the autonomic nervous system.
Step-by-step explanation:
The medical term that refers to difficulty swallowing food and/or liquids is D. Dysphagia. Deglutition, which is the process of swallowing from the mouth to the stomach, is a complex activity involving different muscles and the nervous system. Dysphagia can arise from issues with any part of the swallowing process, which includes the voluntary phase, the pharyngeal phase, and the esophageal phase. The other terms, such as Hemiplegia (paralysis of one side of the body), Hypoxia (deficiency in the amount of oxygen reaching the tissues), and Aphasia (loss of the ability to understand or express speech), are related to different medical conditions.
