Which organs of the digestive system come in contact with food?

The organs of the digestive system that come in contact with food are:

- Mouth: The mouth is the first organ of the digestive system that comes in contact with food. It is here that food is chewed and mixed with saliva, which contains enzymes that begin the process of digestion.

- Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. It carries food from the mouth to the stomach by means of peristalsis, a series of involuntary muscle contractions.

- Stomach: The stomach is a J-shaped organ that secretes gastric juices, which contain hydrochloric acid and enzymes that further break down food. The stomach also churns and mixes food, further aiding digestion.

- Small intestine: The small intestine is a long, coiled tube that is the primary site of nutrient absorption. It is lined with villi, small finger-like projections that increase the surface area of the intestine and help to absorb nutrients from food.

- Large intestine: The large intestine is a shorter, wider tube that is responsible for absorbing water and electrolytes from food. It also stores waste material before it is eliminated from the body.
