Answer:
The lungs (purple structures within the thoracic cage) are organs that act as the site for gas exchange. Each lung is conical in shape, very elastic, and spongy in texture. The left lung is divided into two lobes: upper and lower. The right lung is divided into three lobes: superior, middle, and inferior.
