Correct Answer

Explanation

Human lungs are paired organs that are situated in the chest cavity. They are made up of 3 right lobes and 2 left lobes. The right lung has three lobes - right anterior lobe, middle lobe, and right posterior lobe, while the left lung has two lobes - left anterior lobe and left posterior lobe. The right lung is larger than the left lung to accommodate the liver, which is situated on the right side of the body. The lobes are further divided into bronchopulmonary segments, each supplied by its own bronchus and blood vessels. The bronchopulmonary segments are functionally independent units and can be removed individually if needed.
