The body requires oxygen, and the respiratory system is responsible for taking in this vital substance and expelling its byproduct—carbon dioxide. While the primary organs involved in the respiratory system are the lungs, the system is complex and relies on various body parts and tissues to work. From the nose to the diaphragm, all parts must work together to keep this system functioning optimally.

1. Overview

The respiratory system is composed of an upper and lower tract. The only visible part of this entire system is the nose, which belongs to the upper respiratory tract. Also in this section are the nasal cavity, pharynx, and voice box or larynx. The lower respiratory tract includes the windpipe or trachea and the lungs. Various tissues within the lungs also aid in the respiratory process.
