What type are lungs?

Lungs are classified as respiratory organs that are part of the respiratory system. They are spongy, elastic tissues that facilitate the exchange of oxygen and carbon dioxide between the air and the bloodstream. The primary type of lung tissue is alveolar tissue, which is composed of tiny air sacs called alveoli, where gas exchange occurs. Lungs are essential for breathing, as they help to supply oxygen to the body and remove carbon dioxide.
