hello. there are many ways in which bacteria can help your body function. One way is yes, they can act as powerful enzymes which also has a part in the digestion process. Another way is (have you ever thought about it!) when you sweat, your body releases powerful bacteria which helps your body stay moist when needed. Also, in the pancreas or any other gland of the body, helpful bacteria can be mixed in with some of the hormones that we release. Hope this was very helpful, and good luck with your homework. Remember, if you have a science question, i'll answer just add me to friends. :))
