This process is called digestion, turning the food into a semi-liquid form called chyme.A section of the small intestine, showing tiny finger-like projections called villi absorbing nutrients into the bloodstream. Nutrients from the digested food are absorbed in the small intestine, while waste moves to the large intestine, eventually being excreted from the body.So there are basically 5 steps to digestion... which are...-?
