A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
Edema (American English), also spelled oedema (British English), and also known as fluid retention, dropsy and hydropsy, is the build-up of fluid in the body's tissue, [1] a type of swelling. [4] Most commonly, the legs or arms are affected. [ 1 ]
Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange, most often leading to shortness of breath (dyspnea) which can progress to hypoxemia and respiratory failure.
Four million per year [ 12 ][ 13 ] Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [ 3 ][ 14 ] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [ 15 ] The severity of the condition is variable.
Interstitial lung disease. Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and ...
The invading organism starts multiplying, thereby releasing toxins that cause inflammation and edema of the lung parenchyma. This leads to the accumulation of cellular debris within the lungs. This leads to consolidation or solidification, which is a term that is used for macroscopic or radiologic appearance of the lungs affected by pneumonia.
A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays [3] and around 1% of CT ...
The lamina propria is a thin layer of connective tissue that forms part of the moist linings known as mucous membranes or mucosae, which line various tubes in the body, such as the respiratory tract, the gastrointestinal tract, and the urogenital tract. The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath ...
