Question

Given below are two statements:
Statement I : Our lungs have two parts – the left and right lungs.
Statement II : structurally two parts of the lungs are different from each other. In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Answer 1

The Correct Option is A

To determine the correctness of the given statements regarding human lungs, let's analyze each statement based on anatomical and physiological knowledge.

1. Statement I: Our lungs have two parts – the left and right lungs.
   • This statement is correct. Humans have two lungs, located in the thoracic cavity. The right lung is located on the right side, and the left lung is on the left side. They are separated by the heart and other structures in the mediastinum.
2. Statement II: Structurally two parts of the lungs are different from each other.
   • This statement is also correct. The right lung typically has three lobes – the superior, middle, and inferior lobes – while the left lung has two lobes – the superior and inferior lobes. Additionally, the left lung is slightly smaller to accommodate the space occupied by the heart, which is more inclined toward the left side of the thoracic cavity.

Given the examination of the anatomical structure of the lungs, it is clear that both statements are correct.

Thus, the most appropriate answer from the options given is: "Both Statement I and Statement II are correct."
