The [blank_start]largue intestine[blank_end] is the last stage of the digestive system. Any [blank_start]food[blank_end] that the body doesn't need or can't use is sent to it and later leaves the body as waste. This solid waste is then stored in the [blank_start]rectum[blank_end] until it is excreted via the [blank_start]anus[blank_end].
Food hangs out in the stomach for around four hours. While the food sits there, more [blank_start]enzymes[blank_end] go to work on it, breaking down things like [blank_start]proteins[blank_end] that our bodies can use. The stomach kills a lot of bad [blank_start]bacteria[blank_end] as well, so we don't get sick.
