The food is now in a simple form. It passes through

                    the walls of the small intestines into the blood. The
                    blood carries it to all parts of the body.

                    The undigested food and water in the small intestine
                    pass into the large intestine        . The large intestine allows

                    water and leftover useful substances to pass back into
                    the blood. The undigested food remains inside.

                    The undigested food passes into the large intestine.

                    The blood vessels in the walls of the large intestine
                    absorb  the  extra  water.  The  semi-solid  waste  is
                    passed out through the anus             when we go to the toilet

                    and defecate in the morning.
