The research area of airway focuses on studying the structure and function of the human respiratory system, particularly the airways through which oxygen enters and carbon dioxide exits the body. This includes studying conditions such as asthma, chronic obstructive pulmonary disease (COPD), bronchitis, and other respiratory diseases that affect the airways. Researchers in this field often investigate new treatments, diagnostic techniques, and preventative measures to improve the health and quality of life for individuals with respiratory conditions. Additionally, studies may also focus on understanding the mechanisms of airway inflammation, smooth muscle contraction, mucus production, and airflow regulation within the respiratory system.
