The Gastrointestinal System - Introduction

Question 1

Why is the the gastrointestinal system important?

Answer 1

• Without adequate nutrition, the body cannot function.
• Without food, you die. The G.I. tract allows food to be broken down into molecules small enough to enter the cells of the body.
• The different parts of the G.I. tract are specialised for different roles in either mechanical or chemical digestion.
