QUESTION 31 Which of the following statements is false with regards to deglutition? The epiglottis elevates to cover the nasopharynx. Sensory receptors are stimulated resulting in a swallowing reflex. Peristalsis of the esophagus propels food toward the stomach. A bolus of food is forced into the pharynx. Tongue blocks the mouth.

Step 1
Deglutition involves several coordinated actions to move food from the mouth to the stomach. These actions include the formation of a bolus, the closure of the nasopharynx, the stimulation of sensory receptors, the peristaltic movement of the esophagus, and the Show more…

Which of the following statements about swallowing (deglutition) is FALSE? during swallowing, the larynx is elevated and the epiglottis swings closed the pharyngeal phase of swallowing involves movements of the pharyngeal constrictor muscles swallowing begins as a voluntary act and continues as a reflex upon completion of the buccal phase of swallowing, the bolus has entered the esophagus In red blood cells, the enzyme carbonic anhydrase converts ________ into carbonic acid. carbon dioxide and water 2,3-bisphosphoglycerate hemoglobin lactic acid

Which of the following is NOT true about deglutition (swallowing)? All of the above answers are correct. The involuntary portion of swallowing takes place in the pharynx. The epiglottis aids in moving food into the esophagus. The mouth, pharynx, and esophagus all facilitate swallowing.

Which of the following statements about movement of food through the gut is false? Select one: a. The inner circular muscle and outer longitudinal muscle layers in the gastrointestinal tract propel food unidirectionally towards the anus. b. The order of food passage through the small intestine is duodenum, jejunum and ileum, respectively. c. Sphincters are rings of circular smooth muscle and they are normally constricted to control the passage of food through the alimentary canal. d. The epiglottis and pharynx prevent food entry into the trachea. e. The waves of muscle contraction that propel food through the gut are called peristalsis.
