visceral pleura
Visceral Pleura
A pleura is a serous membrane that lines the lungs and chest cavity of humans and mammals. It is a closed area that helps the lungs during respiration.
The visceral segment of the serous membranes encases the internal organs while the parietal segment is responsible for lining the body wall. Serous membranes which care for the needs of the lungs are known as pleurae while the serous membranes which care for the abdominal cavity are known as peritoneum, but are also referred to as peritoneal membranes.
The outer layer of a serous membrane is called the parietal layer and is always attached to the surrounding tissues. The inner layer is called the visceral layer and is firmly attached to the organ it covers
The pleural membrane is a double-layered serous membrane found in the thoracic cavity. The outer layer is called the parietal pleura and lines the thoracic wall, and the inner layer is called the visceral pleura and covers the lungs. The membranes produce lubricating serous fluid that causes them to adhere closely to one another. This holds the lungs to the thoracic wall allowing easier movement during breathing.
In human anatomy pleural is the area surrounding each of the lungs, which lines the thoracic cavity. It is a thin serous membrane coat, essentially to protect the lungs.
The pleural membrane which contains fluid to prevent friction
Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall. The inner pleura, visceral pleura covers the lungs and adjoining structures.
Areolar tissue is widespread. it is found in the skin, glands, in the organs of the respiratory and digestive systems, and in the serous membrane that surrounds the lungs and intestines.
Visceral and parietal visceral- covers the lungs, thin serous membrane parietal- lines the inner chest wall and covers diaphram
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 (or visceral pleura).
Serositis is the inflammation of serous tissues throughout the body. Serous tissues line the heart, lungs, and abdomen.
Serous membranes line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium. Serous fluid lubricates the membrane and reduces friction and abrasion when organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall. Serous membranes have special names given according to their location. For example, the serous membrane that lines the thoracic cavity and covers the lungs is called pleura.
