|---|---|
| What are the two types of digestion? | Mechanical and chemical digestion |

| What is the wave-like ripple of the muscle layer of the digestive system? | Peristalsis |
| How do we mechanically digest our food? | Mastication |
| What are the enzymes responsible to chemical digestion? | amylase, proteases and lipase |
| What is the "hunger hormone"? | Ghrelin |
| What does Cholecystokinin (CCK) do? | A hormone that responds to fats and proteins and triggers to release digestive enzymes to break them down? |
| Which organ secrete digestive enzymes into small intestine? | Pancreas |
