Major functions of the digestive system
absorption of food for metabolism (energy and growth and repair of tissues)
mechanical and chemical digestion
Mechanical digestion: breaking down large pieces of food into small pieces
Chemical Digestion: breaks food into smaller chemicals that can be absorbed by cells in the body

Contribute to the breakdown of foodstuffs
Teeth, tongue, gallbladder, salivary glands, liver and pancreas
Alimentary Canal /GI Tract
digests food and absorbs the building blocks
