A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region.
Neo-natal and later lung collapse may be due to lung infection, or possibly to a malfunction in the epiglottis, causing the in-breath to draw air into the digestive tract rather than the lungs. A short term malfunction of this sort may be perpetuated by the resulting colic creating a feedback loop that interrupts the correct breathing process.
A Peritoneovenous shunt: (also called Denver shunt) [2] is a shunt which drains peritoneal fluid from the peritoneum into veins, usually the internal jugular vein or the superior vena cava. It is sometimes used in patients with refractory ascites. It is a long tube with a non-return valve running subcutaneously from the peritoneum to the ...

If the cat does approach, you can extend your hand or fingers, let the cat smell it, and decide if they want you to pet them. If they do, they may lean into your hand, which is a good sign that a ...
The lung structure is important for the mechanism of ventilation-perfusion coupling. Pleura (plural: pleurae) is a single membrane surrounding the lung. It folds back to form two layers, and each layer is called parietal pleura and visceral pleura.
Pulmonary laceration, in which lung tissue is torn or cut, differs from pulmonary contusion in that the former involves disruption of the macroscopic architecture of the lung, [1] while the latter does not. [2] When lacerations fill with blood, the result is pulmonary hematoma, a collection of blood within the lung tissue. [3]
