@ -28,3 +28,12 @@ There are 3 main sphincters associated with digestion:
2. Pyloric - connects the stomach to the duodenum (small intestine)
3. ileocecal valve - Connects the small intestine to the large intestine

# Digestion
**Mechanical digestion refers to the physical treatment that food undergoes** while it is in the intestinal tract
Chemical digestion refers to the breakdown of large molecules in food into smaller components, primarily by the action of **enzymes**.
- Enzymes are a protein that speeds up the rate of a chemical reaction without being altered in the process.
- Enzymes usually end in -ase and begin with the name of whatever they are working to digest:
- Amylase digests amylose
- Maltase digests maltose
