Digestive System Overview
- The digestive system is essential for breaking down food into chemical substances for energy and growth.
- Functions include obtaining nutrients and energy from food.
Components of the Human Digestive System
- Comprises seven main parts: mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus.
Mouth and Its Functions
- Teeth: Break down and crush food while chewing.
-
Saliva:
- Aids in digesting starch into sugar.
- Facilitates easy swallowing of food.
- Tongue: Mixes food with saliva to assist in digestion.
Pharynx (Throat)
- Responsible for pushing food from the mouth into the esophagus after swallowing.
Esophagus
- A long muscular tube that connects the throat and stomach.

Stomach
- A muscular organ that mixes food with stomach acid and digestive juices (enzymes).
- Transforms food into a soupy liquid over a few hours before pushing it into the small intestine.
Small Intestine
- A winding tube over six meters long.
- Functions:
- Breaks down food into simple nutrients using juices from the pancreas and liver.
- Absorbs nutrients through its walls, which are then transported to the bloodstream and distributed throughout the body.
Large Intestine
- A tube extending from the end of the small intestine to the anus.
- Absorbs water from undigested food, transforming it into solid waste for elimination through the anus.
