Can anyone name the 2 different ways we breakdown food in our bodies?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

When we eat food begins to be broken down immediately. Our teeth do the first and the big work (mechanical digestion) and the enzymes within the saliva in our mouth begin the breakdown of the food.

The food is further broken down within the stomach by the stomach acid and then the liver does its part by releasing bile as the food leaves the stomach and enters the small intestine. (chemical digestion)

M$The digestive system is divided into 2 components: (1) break down (mouth and stomach) and (2) absorption ... have them write the name of each food item next to each picture. ... That's because the three food groups help your body in different ways. ... That way our bodies can get the most out of the foods we eat. ...
