Answer:

the organs of the digestive system are:

Mouth: The mouth is the region where the first processes of digestion begins. Saliva in the mouth mixes with the food as we chew it.

Pharynx and the esophagus:

Food travels from the mouth to the pharynx and esophagus. In the pharynx, swallowing takes places partially as well as non- partially.

Stomach: The stomach is the organ where most of the digestion takes place. The stomach secretes various enzymes for the digestion of food.

Small intestine: The small intestine comprises of  duodenum, jejunum, and ileum. Enzymes released by the pancreas and bile from the liver help in digestion here. Re-absorption of the nutrients takes place here.

Large intestine: The large intestine comprises of colon, rectum and anus. The excretion of waste takes place here.
