The final organ in the digestive system
is the large intestine. While no digestion
occurs here, this is a very important step.
As the remaining undigested food passes through, the large intestine reabsorbs available water back into the body. The
water is taken into the blood through
capillaries in the intestinal wall. Then the
blood takes the water and redistributes it
to other cells. What is left is the remaining material from food that the body does not need. The large intestine then passes this
remaining waste out of the body.
