1. visceral pleura

   The pulmonary pleurae (sing. pleura) are the two opposing layers of serous membrane overlying the lungs and the inside of the surrounding chest walls. The inner pleura, called the visceral pleura, covers the surface of each lung and dips between the lobes of the lung as fissures, and is formed by the invagination of lung buds into each thoracic sac during embryonic development. The outer layer, called the parietal pleura, lines the inner surfaces of the thoracic cavity on each side of the mediastinum, and can be subdivided into mediastinal (covering the side surfaces of the fibrous pericardium, oesophagus and thoracic aorta), diaphragmatic (covering the upper surface of the diaphragm), costal (covering the inside of rib cage) and cervical (covering the underside of the suprapleural membrane) pleurae. The visceral and the mediastinal parietal pleurae are connected at the root of the lung ("hilum") through a smooth fold known as pleural reflections, and a bell sleeve-like extension of visceral pleura hanging under to the hilum is known as the pulmonary ligament. Between two pleurae is a potential space called the pleural cavity (also pleural space), which is normally collapsed and filled with only a tiny amount of serous fluid (pleural fluid) secreted by the pleurae, and is clinically considered vacuumous under healthy conditions. The two lungs bounded by parietal pleura, almost fill the thoracic cavity.

1. visceral pleura

   The visceral pleura is a thin layer of serous membrane that covers the surface of the lungs and dips into the fissures between the lobes. It is one of the two layers of pleura, the other being the parietal pleura. This membrane helps to provide lubrication to reduce friction between the lungs and the chest wall during breathing.

1. Visceral pleura

   Each lung is invested by an exceedingly delicate serous membrane, the pleura, which is arranged in the form of a closed invaginated sac. A portion of the serous membrane covers the surface of the lung and dips into the fissures between its lobes; it is called the pulmonary pleura. The visceral pleura is derived from mesoderm. The visceral pleura is attached directly to the lungs, as opposed to the parietal pleura, which is attached to the opposing thoracic cavity. The space between these two delicate membranes is known as the intrapleural space. Contraction of the diaphragm causes a negative pressure within this space and forces the lungs to expand, resulting in passive exhalation and active inhalation. This process can be made forceful through the contraction of the external intercostal muscles, forcing the rib cage to expand and aiding to the negative pressure within the intrapleural space, which causes the lungs to fill with air.
