Final answer:
The statement is true; the oropharynx is the part of the pharynx that is continuous with the mouth and is involved in both respiration and digestion.
Step-by-step explanation:
The statement that the portion of the pharynx continuous with the mouth is termed the oropharynx is true. The pharynx is a tube that consists of skeletal muscle lined with a mucous membrane and extends from the nasal and oral cavities to the esophagus and larynx. It is divided into three regions: the nasopharynx, the oropharynx, and the laryngopharynx. Specifically, the oropharynx lies inferior to the nasopharynx and is continuous below with the laryngopharynx. It serves as a passageway for both air and food, indicating its dual role in respiration and digestion. The oropharynx is flanked by the nasopharynx, oral cavity, and laryngopharynx and is lined with stratified squamous epithelium. Therefore, it is accurate to state that the oropharynx is the part of the pharynx that is continuous with the oral cavity and is involved in both breathing and the digestive processes.
