What is the components of the lungs?

The lungs consist of several key components, including the bronchial tree, alveoli, pleura, and pulmonary blood vessels. The bronchial tree includes the trachea, bronchi, and bronchioles, which facilitate airflow. Alveoli are tiny air sacs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. The pleura is a double-layered membrane surrounding the lungs, and the pulmonary blood vessels transport blood to and from the lungs for oxygenation.
