What is the purpose of the respiratory system?
|
The respiratory system works iin close combination with the circulatory system to provide a constant supply of oxygen to every cell in the body and to remove all gaseous waste (carbon dioxide or CO2) from the body. Its structure allow life-giving gas exchange between the blood and the atmosphere. This is the primary function of the respiratory system.

These include vocalizations (speech), or the production of sound as air passes over the vocal cords, assistance with abdominal compression which occurs during mictruition (urination), defecation, and parturition (childbirth) and the natural reflexes of coughing and sneezing which assure that the respiratory system is kept clean.
