Explain the roles of the satiety and feeding centers. Where are they located?

Summary Introduction

To explain: The role of satiety and feeding centers.

Introduction: The digestive system of the human comprises several organs and accessory digestive organs that constitute to make the complete gastrointestinal (GI) tract. The GI tract extends from the anterior opening (mouth) and ends in the posterior opening (anus).
