Hi this is Rachael Richardson with Nutrolution in Miami Beach, Florida. In this clip we are talking about why do we have a digestive system and I have looked at this question and I thought wow that's a funny question, what would we do without our digestive system? Well in reality I guess there are animals out there or plants that don't have digestive system but we absolutely need ours and the reason is because we go through so many nutrients or such complex animals that we need tons and tons of vast amounts of nutrition and the best way to deliver that is through eating by mouth and having a well functioning ideally digestive system that helps to break down those foods with all kinds of complicated enzymes and bacteria and other processes involved and then actually uses our little micro villi they're called. They're finger like projections sticking out everywhere in our digestive system and using those to absorb our nutrients and then transport those nutrients both to the blood to the cells through the liver and many other places so we absolutely could not survive without a healthy functioning digestive system. This has been Rachael in Miami Beach, Florida with Nutrolution.
