each lung lobe is divided into many lobules.

there are two lungs on the right side of the trachea, but only one lung on the left

Explanation:

• Each lung is divided into lobes: The right lung has three lobes (upper, middle, lower), and the left lung has two lobes (upper and lower).
• Each lung lobule contains many alveoli: Lobules are the smallest subdivisions of the lungs visible to the naked eye, and each lobule contains numerous alveoli which are the sites of gas exchange.
• Each lung lobe is divided into many lobules: Larger lobes are further divided into smaller lobules.
• Each alveolus is not further divided into sub - alveoli: Alveoli are the terminal air sacs in the lungs.
• There are not two lungs on the right and one on the left: There are two lungs (a right lung and a left lung). The right lung has three lobes and the left has two.

Each lung is divided into lobes, Each lung lobule contains many alveoli, Each lung lobe is divided into many lobules.
