To determine which of the statements is true, let's analyze each option step by step:

1) Right lungs is greater than left lungs: This statement is not accurate. In reality, the right lung is divided into three lobes (superior, middle, and inferior), while the left lung only has two lobes (superior and inferior). However, the total volume of both lungs is approximately the same.

2) The structural and functional unit of the lungs is alveoli: This statement is correct. The alveoli are tiny air sacs located at the end of the bronchioles in the lungs. They are responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.

3) Lungs are non-muscular: This statement is not entirely accurate. While the lungs themselves do not contain muscles, they are surrounded by the diaphragm and other respiratory muscles that aid in the process of breathing.

Based on the analysis, option (2) is the only true statement. Therefore, the correct answer is (2) - the structural and functional unit of the lungs is alveoli.
