Question 17

Know the 2 types of digestion

Answer 17

Mechanical digestion:

Chemical digestion:
* chemically breaks down food via enzymes
* saliva is produced by the parotid, sublingual, and submandibular glands; it is 97-99.5% water, but also contains electrolytes, lysozyme, and the digestive enzymes salivary amylase and lingual lipase.
