The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. In air-breathing vertebrates like human beings, respiration takes place in the respiratory organs called lungs.
Physiological respiration occurs across the respiratory system, which includes the upper and lower respiratory tracts. The upper respiratory tract is composed of the nasal cavity, sinuses, pharynx and larynx, while the lower respiratory tract includes the trachea, lungs, bronchi and the diaphragm. Physiological respiration is also known as ventilation and breathing, and it involves inhalation and exhalation processes. Ventilation occurs involuntarily, but a person can modify breathing. Healthline notes that respiration is important because the body cannot store oxygen.
