Explanation:
Detailed explanation-1: -Humans have two lungs, one on the left and one on the right. They are situated within the thoracic cavity of the chest. The right lung is bigger and heavier than the left, which shares space in the chest with the heart.
Detailed explanation-2: -The lungs are not equal in size. The right lung is shorter, because the liver sits high, tucked under the ribcase, but it is broader than the left. The left lung is smaller because of the space taken up by the heart (see diaphragm for an image of this).
Detailed explanation-3: -It is FALSE. The left lung is approximately 10% smaller than the right one. This extra space on the left leaves room for the heart.
