What is Breathing?
- Gas exchange is a procedure that is vital to life. There are two separate phases to the process of breathing. Inhalation is the first phase, also known as inspiration, while expiration is the second phase, also known as exhalation.
- Air enters your lungs when you inhale (breathe), and the oxygen in that air travels to your blood and at the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out).
- The physical characteristics of the lung have an impact on both the intrapleural and alveolar pressures. However, both the atmospheric and intrapulmonary air pressures are necessary for breathing.
