The word 'pulmonary' relates to the lung. For example, pulmonary hypertension is a condition referring to high blood pressure of the lungs, explains by Mayo Clinic.
Another example is pulmonary fibrosis, which refers to scarring of the lungs. The condition is caused by exposure of the lungs to inflammatory disease, environmental agents or certain drugs, explains WebMD. Symptoms of pulmonary fibrosis include cough, shortness of breath and an inability to tolerate moderate exercise. Treatment options are limited, with lung transplantation the only available therapeutic option. Pulmonary fibrosis may also lead to pulmonary hypertension due to decreased oxygen levels in the blood.
