Digestive System Model

A digestive system model is a visual or physical representation of the human digestive tract used for teaching, demonstration, or study. It helps illustrate how food moves through the body and how digestion occurs step by step.

 Key Parts Typically Shown

A good model will include the main organs of the digestive system:

• Mouth – where digestion begins (chewing + saliva)
• Esophagus – tube that carries food to the stomach
• Stomach – breaks down food using acids and enzymes
• Small Intestine – absorbs nutrients into the bloodstream
• Large Intestine (Colon) – absorbs water and forms waste
• Rectum & Anus – expel waste from the body

Accessory organs often included:

• Liver – produces bile
• Gallbladder – stores bile
• Pancreas – produces digestive enzymes
