Mesothelioma Pleural Cavity

Mesothelioma Pleural Cavity

Mesothelioma Pleural Cavity, In human anatomy, the pleural cavity is the body cavity that surrounds the lungs. The pleura is a serous membrane that folds on itself to form a structure with two layers of membrane. The thin air between the two pleural layers is known as the pleural cavity that normally contains a small amount of pleural fluid. The outer pleura (parietal pleura) is attached to the chest wall. The interior pleura (visceral pleura) covers the lungs and adjacent structures, ie. blood vessels, bronchi and nerves.

Parietal pleura is very sensitive to pain, when the visceral pleura is not because of its sensory innervation

Functions ( Mesothelioma Pleural Cavity )
The pleural cavity, with its associated pleurae, aids optimal functioning of the lungs during respiration. Pleural effusion also contains a liquid, which allows you to glide effortlessly pleura against each other during ventilation. Of surface tension to close the pleural fluid also leads to certification, the lung surfaces of the chest. This physical relationship allows optimal inflation in the alveoli during breathing. Movements pleural cavity of the chest pass to the lungs, especially during the heavy breathing. This is due to close against the chest wall transmits pressures the surface of the visceral pleura, and then the lung itself.

Structure ( Mesothelioma Pleural Cavity )
In humans, there is no anatomical connection between the pleural cavity left and right. Therefore, in case of pneumothorax, and others in the lungs to function normally, unless there is a tension pneumothorax or simultaneous bilateral pneumothorax, which can hide the contralateral parenchyma, blood vessels and bronchi.

Visceral pleura receives its blood supply of the bronchial circulation.

Development ( Mesothelioma Pleural Cavity )
Initially, intraembryonic coelom is a continuous space. During the development of this space form a partition, the pericardium, pleural and peritoneal cavities. Movies and a pair of membranes separated pleuropericardial coelomic cavity into four parts. From splanchnopleura (visceral mesoderm layer) to develop and visceral pleura somatopleura (mesoderm layer of the crown) to develop the parietal pleura.

Pleural fluid ( Mesothelioma Pleural Cavity )
Pleural fluid is a serous fluid produced by the normal pleura. Vai produced by the parietal circulation (the ribs in the arteries) by mixing and absorbed by the lymphatic system. Thus, the pleural fluid is constantly produced and reabsorbed. In a normal 70 kg man, a few milliliters of pleural fluid is present within the intrapleural space. [2], large amounts of fluid can accumulate in the pleural than a nominal value of resorption. Normally, the amount of resorption increases physiological response to water retention, which increases the reabsorption of up to 40 times the normal level before a significant amount of fluid accumulates in the pleural space. This profound increase in the production of pleural fluid or to prevent some reabsorption of the lymphatic system, it is necessary to accumulate in the pleural fluid.

Mesothelioma Pleural Cavity, Pleural effusion noted in localized pulmonary embolism (PE), probably the result of increased capillary permeability by cytokines or inflammatory mediator release of platelet-rich thrombus.

When the accumulation of pleural fluid is noticed cytopathological evaluation of liquids, as well as clinical microscopy, microbiology, chemical studies, tumor markers, determination of pH, and other esoteric tests as diagnostic tools to determine the causes of abnormal accumulation. The gross appearance, color, clarity and odor can be useful tools for diagnosis. The presence of congestive heart failure, infection or tumors within the pleural cavity are the most common causes that can be identified using this approach. Mesothelioma Pleural Cavity

In spite of all diagnostic tests available today, many of idiopathic pleural origin. This can be quite annoying for the patient, family and doctors involved. If symptoms persist severe, more invasive techniques may be required. Despite the lack of knowledge about the cause of the effusion, treatment may be necessary to relieve the most common symptom is dyspnea, which can be very debilitating. Thoracoscopy has become the mainstay of invasive procedures, closed pleural biopsy has fallen into disuse. Mesothelioma Pleural Cavity
