What are the 2 factors of the respiratory system?

The two key factors of the respiratory system are gas exchange and ventilation. Gas exchange refers to the process of oxygen being absorbed into the bloodstream and carbon dioxide being expelled from it, primarily occurring in the alveoli of the lungs. Ventilation involves the movement of air in and out of the lungs through inhalation and exhalation, allowing for this gas exchange to take place efficiently. Together, these factors enable the body to maintain adequate oxygen levels and remove carbon dioxide.
