About This Answer
Humans have two lungs (left and right) enabling efficient oxygen exchange. According to the National Institutes of Health, lungs contain millions of alveoli for gas exchange. The American Lung Association documents how the two-lung system provides redundancy and capacity. Pulmonologists note that the left lung is slightly smaller to accommodate the heart. The two-lung configuration represents an efficient respiratory design for mammals.
