The visceral and parietal layers become continuous in front of and behind the root of the lung. Below the root of the lung, a fold, the pulmonary ligament extends downward along the medial surface of the lung. It allows for the distension of the pulmonary veins. In development, the lungs ...
The respiratory surface area varies from 30 sq m to 100 sq m (with a deep breath).Each lung is covered with pleura, and the pleural cavity contains a small amount of fluid, which allows the lung to slide easily in the thoracic cavity during respiratory movement.Venous blood enters the ...
The surfaces of the lungs are costal and medial. Costal Surface It’s large, smooth, and convex. It’s covered by the costal pleura and endothoracic fascia. Connections It’s related to the lateral thoracic wall. (In embalmed and tempered lung, the costal surface presents impressions of the...

The lungs are divided into lobes by double folds of pleura which form fissures. From the lateral view the fissures are seen as thick lines that extend across the costal surface. The left lung has only one fissure (oblique fissure of left lung) which divides it into superior and inferior ...
Paired, air-filled respiratory sacs, usually in the anterior or anteroventral part of the trunk of most tetrapods. They lie within the coelom and are covered by peritoneum. In mammals they are within special chambers of the coelom known as pleural cavities and the peritoneum is termed pleura....
