Summary Introduction

Introduction:

Respiration, also called as breathing is a process where oxygen is inhaled into the lungs and carbon dioxide is exhaled from the lungs. One respiratory cycle is a complete breath in and out. The diaphragm has an essential role during respiration. The diaphragm is a dome shaped muscle that separates the thorax from the abdomen. It plays an important role in respiration. The transverse abdominal muscle is a thin sheet of muscle that lies deep to the internal oblique muscle and runs anteriorly and laterally. This muscle compresses the visceral organs and ribs thereby providing thoracic stability.
