The chest wall is made up of the ribs and the muscles between the ribs.

The lungs occupy most of the space in the thoracic cavity. The heart sits between the right and left lung. The lungs are soft and spongy because they are mostly air spaces surrounded by the alveolar cells and elastic connective tissue. Each lung is enclosed by a double-layered serous membrane, called the pleura.The visceral pleuron is firmly attached to the surface of the lung. Visceral pleura is continuous with the parietal pleura that lines the wall of the thorax. The small space between the visceral and parietal pleurae is the pleural cavity.he lungs occupy most of the space in the thoracic cavity. The heart sits between the right and left lung.
