Chapter 14, Problem 30SAE

Summary Introduction

To review:

The precise composition of feces.

Introduction:

The feces are the prime undigested materials that cannot be further digested by the enzymes of the gastrointestinal tract. Feces are the final products of digestion, which cannot be further digested. All important nutrients and vitamins present in food are absorbed from the food by the small intestine.

The remaining water and vitamins are absorbed by the inner linings of large intestine. After all these absorption processes, the food forms a semisolid slimy mass of undigested materials called feces.
