system and explain.​

Answer 1

Answer:

The process of digestion begins in the mouth during mastication, where chewing breaks food into small bits and mixes it with saliva. In the small intestine, nutrients are absorbed through the lining of the intestinal wall, and finally, indigestible waste products are pushed into the colon and excreted.
