Are the lungs hollow bags or spongy what does the lung tissue look like where you cut into it what happens when you put this tissue into water?

The lungs are spongy organs rather than hollow bags, composed of a network of air-filled alveoli surrounded by elastic lung tissue. When cut, lung tissue appears light, porous, and somewhat moist due to its structure and the presence of air pockets. If you submerge lung tissue in water, it will initially float because of trapped air, but over time, it may eventually sink as the air is displaced and replaced with water.
