The correct answer is "Dagli alveoli polmonari." The question asks about the composition of the lungs, and the correct answer states that the lungs are made up of alveoli. Alveoli are tiny air sacs located at the end of the bronchioles in the lungs, where the exchange of oxygen and carbon dioxide takes place during respiration. The other options mentioned, such as the heart, liver, pharynx, and epiglottis, are not components of the lungs.
