A. Mechanical Digestion Only B. Chemical Digestion Only C. Both mechanical and chemical digestion D. Neither mechanical and chemical digestion |
What is Large Intestine
What is the place where no digestion occurs here; undigested & unabsorbed materials travel down and out of the body. What is reabsorbed here.
