A bolus is (a) a mass of crushed food moistened with saliva (b) the semisolid material resulting from partial digestion in the stomach (c) the milky emulsified fat absorbed from small intestine (d) indigestible materials that help in movement and absorption of food.
Option A. A food bolus is a mass of crushed food which is moistened with saliva. ∙ The mastication of food that occurs in the mouth with the help of teeth breaks down the food into smaller fragments. As it mixes with the saliva it forms the food bolus. ∙ It is easier for the food to move through the oesophagus in this form so that it can easily reach the stomach.
