Respiratory System

Introduction

The human respiratory system comprises of

  • the nose
  • pharynx (throat)
  • larynx (voice box)
  • trachea (windpipe)
  • bronchi, and lungs.

The respiratory system is divided based on structure and function. The most basic function of the system is to provide oxygen to the body and remove carbon dioxide. Though it also performs some non-respiratory functions.

Classification of Respiratory Function

The respiratory system is divided based on the structure into two distinct parts:

  • Upper Respiratory Sytem
  • Lower Respiratory System

Based on function the system is divided into two zones:

  • Conducting Zone
  • Respiratory Zone
