Structure and Function
The respiratory system performs two major tasks:
•Exchanging air between the body and the outside environment known as external respiration
•Bringing oxygen to the cells and removing carbon dioxide from them referred to as internal respiration

Inhale/Exhale
The passage of air from the external environment to the lung capillaries, bloodstream and out consists of one inhalation and one exhalation.
