Discussion Board: The Breath
Overview
The respiratory system is responsible for ventilation (breathing). Breathing is movement of air inside the lungs (inhalation) and out of the lungs (exhalation). The first breath the newborn takes is the toughest and it requires more energy than a subsequent breath.
Cigarette smoking is responsible for more than 480,000 deaths per year in the United States, including more than 41,000 deaths resulting from secondhand smoke exposure. Smoking causes chronic obstructive pulmonary disease (COPD) in patients.
