Study Notes
Digestive Process
- Food passes through the same digestive tract and needs to be processed into small particles of the same texture
- Crushing food with teeth initiates the processing of food
- Food is wetted with saliva to facilitate smooth passage through the soft-lined canal
Saliva and Salivary Glands
- Saliva is a fluid produced by salivary glands
- Saliva is secreted when we eat something we like, causing the mouth to 'water'
- Saliva contains an enzyme called salivary amylase
Breakdown of Complex Molecules
- Food is complex and needs to be broken down into smaller molecules for absorption in the alimentary canal
- Biological catalysts called enzymes help break down complex molecules
- Salivary amylase breaks down starch (a complex molecule) into simple sugar
