bronchopleural
Air is normally able to pass through the bronchial tree normally is the bronchial tree is open via laminar flow. Breath sounds are heard during auscultation of the chest, using a stethoscope. Normal breath sounds are termed as vesicular breath sounds. However, in conditions such as a pleural effusion where there is air within the pleural cavity, the flow of air becomes disturbed. Therefore, there will be absent breath sounds and if the effusion is large, bronchial breath sounds will be heard which are both abnormal.
Abnormal findings include tumors, viral, fungal, or parasitic infections, and tuberculosis
The pleural effusion is any abnormal amount of fluid all around the lungs. It can result to varying types of medical conditions.
The thin watery fluid that occurs between the pleural membranes is called pleural fluid. This fluid helps to reduce friction between the two layers of the pleura, allowing smooth movement of the lungs during breathing.
The potential space between the pleural membranes is called the thoracic cavity. This is also known as the pleural cavity in some instances.
The pleural cavity is located in between the visceral and parietal of the lungs.
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
The mediastinum.
The two pleural membranes should be touching. If air creates a space between them the air will push the lung down and prevent it from filling with air. This is known as a collapsed lung, or pneumothorax. The air between the pleural membranes must be removed to reinflate the lung.
Each lung lies within the pleural cavity within which the lung expands. The pleural cavity is lined by two transparent elastic membranes called the pleura/pleural membranes. The inner pleuron covers the lung the outer pleuron is in contact with the walls of the thorax and the diaphragm. A thin layer of lubricating fluid between the pleural membranes allows them to glide over each other when the lungs expand and contract during breathing. So your answer is the pleural fluid lies between the pleural membranes.
There are several structures associated with the lower respiratory tract. Those worth mentioning include: the trachea, the bronchi, the bronchial tree, the lungs, and the pleural cavity.
The thin fluid-filled space in the chest between the two pleural layers is called the pleural cavity. This space helps the lungs expand and contract during breathing by reducing friction between the layers of the pleura.
