Question

BlackTom AI · Accepted Answer

Question context: identifying terminology related to the anatomy and physiology of digestion. 
Option 1: 'Mucus' — Mucus is a slippery secretion lining many surfaces, including the esophagus, but it is not a swallowed mass of food; it functions as a lubricant and protective coating, not as the food bolus itself. 
Option 2: 'Gastric Juice' — Gastric juice refers to the stomach contents produced by glands (including acid and enzymes), rather than the mass of ingested food; it is involved in digestion but is not the swallowed lump that travels through the alimentary tract. 
Option 3: 'Chyme' — Chyme is the semiliquid, partially digested food that leaves the stomach and enters the small intestine; it forms after gastric processing, not at the moment of swallowing. So while related to digestion, it is not the initial swallowed mass. 
Option 4: 'Bolus' — A bolus is the term used for a swallowed mass of food that is propelled by swallowing into the esophagus; this word specifically denotes the food mass before digestion proceeds. 
Summary of distinctions: mucus is a protective secretion, gastric juice is digestive secretions inside the stomach, chyme is the digested slurry after stomach processing, and bolus is the act and product of swallowing the food mass. Therefore, the term that matches 'a swallowed mass of food' is the bolus.
