"Pulmonary" refers to anything related to the lungs and the respiratory system. It is derived from the Latin word "pulmo," meaning lung. The pulmonary system is essential for breathing, allowing oxygen to enter the body and carbon dioxide to be expelled. This process is vital for maintaining healthy bodily functions. Common pulmonary conditions include asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis. These conditions can affect breathing and overall lung function. Treatments often involve medications, lifestyle changes, and sometimes therapies to improve lung health and enhance quality of life.
