Question

what is the function of saliva during digestion?
neutralize stomach acid
moisten and lubricate the food, making it easier to swallow
absorb nutrients from the food
break down the food into smaller particles
produce enzymes that digest the food

Explanation:

Saliva moistens and lubricates food for easier swallowing. Stomach acid is neutralized later (e.g., by pancreatic bicarbonate). Nutrient absorption mainly occurs in the small intestine. Chewing breaks food into smaller particles. Salivary glands produce enzymes (like amylase), but the function of saliva itself (as a fluid) is moistening/lubricating.

Answer:

Moisten and lubricate the food, making it easier to swallow
