Respiratory Assessment : Common Landmarks

A Look at Respiratory disorders

The respiratory system functions primarily to maintain the exchange of oxygen and carbon dioxide in the lungs and tissues and to regulate acid-base balance. Any change in this system affects every other body system. Conversely, changes in other body systems may reduce the lungs’ ability to provide oxygen and eliminate carbon dioxide.

The below illustration shows the major structures of the upper and lower airways. The inset
shows the alveoli in detail.


Anatomy and physiology

The respiratory system consists of the airways, lungs, bony thorax, and respiratory muscles and functions in conjunction with the central nervous system (CNS). These structures work together to deliver oxygen to the bloodstream and remove excess carbon dioxide from the body.

The illustrations below shows common landmarks used in respiratory assessment.
