The respiratory system plays a vital role in the inhalation and exhalation of respiratory gases in the human body. It allows for the inhalation of gases such as oxygen in the air which can then be transported by the blood around the body to supply tissues and cells, and the exhalation of waste gases such as carbon dioxide into the air. This free online course enables the learner to explore the structure and functions of the human respiratory system. It outlines the different types of breathing and breathing cycles, and explains the different types of lung capacities.
