What is true about lungs-

Correct option is B

Sol. The lungs have bronchi and bronchioles. The bronchi are the larger tubes that branch into smaller bronchioles within the lungs, through which air is distributed for gas exchange.
Explanation of each option:
· (a) Right lung has two lobes – This is incorrect. The right lung has three lobes, while the left lung has two lobes.
· (b) They have Bronchi and Bronchioles – Correct answer. The lungs have bronchi (main tubes) and bronchioles (smaller tubes) that help in the distribution of air for gas exchange.
· (c) They are covered by pericardium – The pericardium covers the heart, not the lungs. The lungs are covered by a double-layered membrane called the pleura.
· (d) Situated just below diaphragm – This is partially true. The lungs are located above the diaphragm, not directly below it. The diaphragm helps with the breathing process by expanding and contracting the lungs.
