Study Notes
Digestion
- Digestion breaks down food into nutrients, which enter cells.
- Enzymes are biological catalysts that speed up chemical reactions (e.g., saliva).
- Chewing and the physical and chemical action of the stomach are involved in the process.
- 5 stages of nutrition:
- Ingestion: Intake of food
- Digestion: Breaking down of food
- Absorption: Nutrients from digested food are taken up by cells
- Assimilation: Nutrients are distributed through the blood stream for growth and repair.
- Egestion: Removal of undigested waste through the anus.
- Saliva contains amylase, an enzyme.
- The mouth physically breaks down food with chewing.
- The stomach churns food with strong muscles.
- Food travels from mouth to esophagus to stomach.
- Liver produces bile.
- Small intestine absorbs nutrients.
- Large intestine absorbs water and stores solid waste.
- Solid waste exits through the anus.
