Digestion in the mouth Start of digestion Mechanical-chewing Chemical-saliva

Digestion in the stomach Mechanical-churning food Chemical- hydrochloric acid is added Food is changed to a liquidy form called Chyme

Digestion in the small intestine Chemical- bile and trypsin are added Most digestion happens here Digested nutrients are absorbed into the blood through capillaries and sent to all cells
