• B. The semisolid material resulting from partial digestion in the stomach
• C. The milky emulsified fatabsorbed from small intestine
• D. Indigestible materials that helps in movement and absorption

Answer 1

The correct option is A A mass of crushed food moistened with saliva

A bolus is a mass of food that (with animals that can chew) has been chewed at the point of swallowing. Under normal circumstances, the bolus then travels down the oesophagus to the stomach for digestion. Bolus has the same colour as the food that has been chewed by the person and is different from chyme. The bolus is a rolled up ball-like structure formed when the animal is about to swallow. Its pH is alkaline because of the presence of saliva. Thus, option A is correct.
