Question

Which organs perform both mechanical digestion and chemical digestion of food?

1) mouth
2) pancreas
3) small intestine
4) stomach

Answer 1

Answer:

MOUTH

Explanation:

Saliva is an enzyme that starts to break carbohydrates, if any. That's why the mouth also performs Chemical Digestion. Once the food is ready to be swallowed, it is pushed into the Pharynx and into the esophagus*. The esophagus squeezes food with rhythamic muscle contractions-this is called Peristalsis.

Answer 2

Answer:

Organs which perform both mechanical digestion and chemical digestion of food are mouth and stomach. (mainly in mouth)

Explanation:

Both mechanical and chemical digestion occur in the mouth. Teeth grind and break up food (mechanical), while an enzyme in saliva called amylase begins to break down carbohydrates (chemical).Mechanical and chemical digestion begin in the mouth where food is chewed, and mixed with saliva to begin enzymatic processing of starches. The stomach contains hydrochloric acid which helps to chemically digest proteins. Mechanical digestion also occurs in the stomach due to the churning motion.
