What do you already know about the digestive system?

Introduction to Digestive System

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body.

Mouth and Salivary Glands

The process of digestion begins in the mouth, where food is broken down by the action of chewing and mixed with saliva.

Esophagus and Swallowing

Once food is chewed and mixed with saliva, it's swallowed and moves down the esophagus to the stomach.

Stomach and Gastric Juices

The stomach secretes gastric juices that help break down food into a semi-liquid mixture called chyme.

Small Intestine

The small intestine is where most of the digestion and absorption of food occurs, as it is lined with tiny finger-like projections called villi.

Liver and Gallbladder

The liver produces bile, which is stored in the gallbladder and released into the small intestine to help with digestion.

Pancreas and Digestive Enzymes

The pancreas produces digestive enzymes that are released into the small intestine to further break down nutrients.

Large Intestine and Absorption

The large intestine absorbs water and electrolytes from undigested food and prepares for waste elimination.

Rectum and Anus

The rectum stores waste until it is ready to be expelled through the anus as feces.

Digestive System Summary

The digestive system plays a crucial role in breaking down food, absorbing nutrients, and eliminating waste from the body.
