The lungs are divided into two parts, the right and left lungs, to accommodate the heart's position in the thoracic cavity and to optimize respiratory function. This division allows for a more efficient exchange of gases, as each lung can expand and contract independently. Additionally, having two lungs provides a backup system; if one lung is compromised, the other can still function, ensuring that the body continues to receive oxygen.
