Question

Mucus in saliva helps in converting the masticated food particles into a ________.

• A. chyme
• B. succus entericus
• C. bolus
• D. proteoses

Answer 1

The correct option is C bolus

Bolus is a ball-like mixture of food and saliva that forms in the mouth as a result of the process of chewing. Mucus in saliva helps in lubricating and adhering the masticated food particles into a bolus. The bolus further passes down through the oesophagus into the stomach. In the stomach, the food mixes thoroughly with the acidic gastric juice. At this stage, the mass of semi digested food is referred to as the chyme.

Succus entericus or the intestinal juice is a mixture of secretions of the brush border cells of the intestinal mucosa and the secretions of the goblet cells of the intestine.

Proteose is the partially hydrolysed protein in the chyme.
