Greek writer Herodotus, a frequent visitor to Egypt, wrote in the fifth century B.C. about the process, "Having agreed on a price, the bearers go away, and the workmen, left alone in their place, embalm the body. If they do this in a perfect way, they first draw out part of the brain through the nostrils with an iron hook, and inject certain ...
Precision-cut Lung Slices (PCLS) have been instrumental in studying the body's innate responses to viral and, to a lesser extent, bacterial challenges. This system has shed light on which cells become infected within the intact lung, offering insights distinct from in vitro air-liquid interface cultures.
The end-exhalatory lung volume is now well below the resting mid-position and contains far less air than the resting "functional residual capacity". However, in a normal mammal, the lungs cannot be emptied completely. In an adult human, there is always still at least 1 liter of residual air left in the lungs after maximum exhalation. [6]
A lung biopsy is an interventional procedure performed to diagnose lung pathology by obtaining a small piece of lung which is examined under a microscope. [ 1 ] [ 2 ] Beyond microscopic examination for cellular morphology and architecture, special stains and cultures can be performed on the tissue obtained.
In order to listen to the lungs from the back the patient is asked to move their arms forward to prevent the scapulae (shoulder blades) from obstructing the upper lung fields. These fields are intended to correlate with the lung lobes and are thus tested on the anterior (front) and posterior (back) chest walls.
The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
Keeping a wound moist, she notes, is very important, because doing so “facilitates skin cells coming together faster and new skin forming over top of your cut or scrape.”
Bronchoalveolar lavage (BAL), also known as bronchoalveolar washing, is a diagnostic method of the lower respiratory system in which a bronchoscope is passed through the mouth or nose into an appropriate airway in the lungs, with a measured amount of fluid introduced and then collected for examination.
