A digestive system functions in _______.

  1. a. secreting enzymes
  2. b. absorbing compounds
  3. c. eliminating wastes
  4. d. all of the above

Summary Introduction

Introduction: Most animals consume large and complex foods. Large food particles are broken down into smaller monomers in such a form that can be circulated to every cell throughout the body. These functions are carried out by a set of specialized structure present in an organism called as digestive system. Most of the organism undergoes extracellular digestion. Four tasks are mainly carried out by the digestive system: ingestion, digestion, absorption, and elimination.


Reason for correct answer: Digestion of food material starts at the point of the food consumption itself. Varied enzymes are released to break down the food to simpler form. The larger and complex macromolecules are converted to simpler absorbable form. Then, the nutrients are absorbed to respective structures and circulated throughout the body of the organism. At the end of the digestive process, the undigested and unabsorbed materials are expelled out of the organism.

Option d. is given as “all of the above”. This is correct because the digestive system performs all the given functions. It secretes enzymes, absorbs compounds, and also helps in excreting toxic compounds out of the body.

Hence, the correct answer is option d.

Reasons for incorrect answer:

Option a. is given as “secreting enzymes”. Digestive system secretes a series of enzymes called as digestive enzymes that help to break down the complex macromolecules into simpler monomers...
