The effect of porcine pancreatic elastase and mechanical ventilation on tissue elastic recoil was examined in excised dog lung lobes. Lobes incubated for one hour with an elastase-buffer mixture showed a significant (P less than 0.001) left shift of the liquid-filled pressure-volume curve at all pressures measured (0 to 12 cm H2O) when compared to lobes treated with buffer only.



If the patient has  Elastin breakdown and the resultant loss of lung elastic recoil is a hallmark of pulmonary emphysema in susceptible individuals as a consequence of tobacco  Video explaining Properties of the Lungs-- Compliance, Elasticity, Resistance, and Surface Tension for Anatomy & Physiology. This is one of many videos. Learn about how muscle contraction and lung recoil actually help the lungs change their volume with every breath! Rishi is a pediatric infectious disease  Work of breathing does not refer to expiration, which is entirely a passive process caused by elastic recoil of the lung and chest cage.

An attempt was made to determine if emphysema and static lung recoil were related in a group of 65 excised human lungs ▷.

Elastic recoil of lungs

- for a particular lung volume: the elastic recoil of the lung during expiration is always less than the distending transmural pressure gradient required during inspiration at the same volume. Time dependence of pulmonary elastic behaviour.

With inhalation, the intrapleural pressure (the pressure within the pleural cavity) of the lungs decreases. Elastic recoil is inversely related to lung compliance. Now when the surgeon removes the areas of emphysematous lung, the elastic recoil increases, the chest wall is drawn in, and the diaphragm rises.

Studies in adults have related the PV char- acteristics of the lung to structural  with air during inspiration. They must be elastic to recoil and push air out during expiration. The compliance of the lungs is demonstrated by an isolated lung in a   2 Jun 2010 Air vs. saline-filled pressure volume profiles demonstrated loss of lung elastic recoil in targeted mice that was contributed by both tissue  26 Jan 2021 Elastic arteries are the largest in the body such as the aorta and pulmonary artery . An elastic artery is also known as a conducting artery, because  In a restrictive lung disease, the compliance of the lung is reduced, which increases the to breathe out quickly, because of the high elastic recoil of the stiff lungs.

A dense labyrinth of elastic fibers and other matrix elements within the lung parenchyma, along with surface tension at the alveolar air-liquid interface, confers this important mechanical property. Elastic recoil is the tendency of the lungs to recover as people breathe in and out. When people inhale, their lungs fill rapidly with air. Surfactant, a lubricant in the lungs, changes the surface tension in the lungs and allows the alveoli, tiny bubble-like structures lining the lungs, to expand.

When the muscles that expand the thorax are relaxed, the lungs contract by their own elastic recoil forces, so that breath is expired. In other words, no muscles 

A pneumothorax, can occur with trauma or surgery. In this instance, the chest wall is pierced without damaging the lung. The loss of elastic recoil of the lung affects the pressure difference between the interior of the alveoli and the pleural surface of the lungs, that is, the transpulmonary pressure. As a result, a lung of high compliance, like the emphysematous lung, expands to a greater extent than the one of low compliance, when both are exposed to the same increase in transpulmonary pressure.
