What are the main structural components of the lungs?
The lungs are divided into lobes, with the right lung having three lobes and the left lung having two. The primary structural components include the airways (trachea, bronchi, and bronchioles), alveoli, blood vessels, and connective tissue. The trachea bifurcates into the main bronchi, which further divide into smaller bronchi and bronchioles, culminating in the alveolar sacs where gas exchange occurs.
