Overview of the Respiratory System

The respiratory system is the biological system that engages in gas exchange.

It works with the circulatory system to deliver oxygen from the lungs to the cells, remove the carbon dioxide, return it to the lungs to be exhaled.

Healthy lungs take in about 1 pint of air about 12-15 times per minute.

The organs of the respiratory system include :

• nose

• pharynx

• larynx

• trachea

• two bronchi (one for each lung)

• bronchioles and smaller air passages

• two lungs and the pleura, their covering

• muscles of breathing (intercostal muscles)

• the diaphragm
