Respiratory System Summary

The human Respiratory System is of key importance since it supplies oxygen to our body cells to live and function properly. Our body cells require oxygen to burn fatty acids and sugars (carbohydrates/glucose) in the production of energy. Another important function of the Respiratory System is get rid of excess levels carbon dioxide in your blood, which could harm your body’s organs.

Respiratory System Description

The role, main functions and main organs of this human body system are discussed below.

Role of the Respiratory System

The Human Body Respiratory System (also called the Gas Exchange System) is the group of tissues and organs that allow you to breathe air to supply oxygen to your cells throughout the body. It enables the body to get rid of carbon dioxide by breathing air out. Respiration is simply the exchange of oxygen for carbon dioxide. The Respiratory System also performs other important functions as discussed below.

Main Functions Respiratory System

The primary functions of the Respiratory System are:

Gas Exchange Respiratory Function: External gas exchange is the movement (external respiration) of inhaled oxygen (O2) within the alveoli to the bloodstream. System then expels (exhaling) other gases such as carbon dioxide, a byproduct of cellular metabolism from the lungs. Carbon dioxide (CO2) is transferred (internal respiration) from the bloodstream to the alveoli and excess carbon dioxide is exhaled. The Alveoli is tiny sacs within our lungs.

Homeostatic Regulation Respiratory Function: The homeostatic regulation function regulates the pH in the blood by regulating carbon dioxide.

Protective Respiratory Function: The Respiratory Human Body System protect us from inhaled pathogens and irritating substances.

Vocalization Respiratory Function: The Respiration System facilitates speech by vibrating the vocal cords in the larynx (voice box) to produce sound.

Olfaction/Smelling Respiratory Function: Olfaction is the sense of smell that occurs as air passes over olfactory fibers in the nasal cavities. Olfactory fibers transmit nerve impulses about odors to the nervous system, which is perceived as smell.


The organs of the Respiratory System are the nasal cavity, pharynx, larynx, trachea, bronchi and lungs.
