Pulmonary diseases refer to a group of disorders that affect the lungs and respiratory system. These diseases can range from chronic conditions like asthma and chronic obstructive pulmonary disease (COPD) to acute illnesses such as pneumonia and pulmonary embolism. Research in the field of pulmonary diseases focuses on understanding the causes, mechanisms, and treatments of these disorders. Scientists and clinicians study various aspects of pulmonary diseases, including respiratory physiology, immunology, genetics, and epidemiology, to improve diagnosis, management, and prevention strategies. Overall, research in this area aims to advance our understanding of pulmonary diseases and develop more effective therapies to improve the quality of life and outcomes for patients with these conditions.
