Air then flows in through the airways (from high pressure to low pressure) and inflates the lungs. When you exhale, the diaphragm and intercostal muscles relax and the chest cavity gets smaller. The decrease in volume of the cavity increases the pressure in the chest cavity above the out...

The application of PEEP in patients with unilateral lung disease may be detrimental if PEEP hyperinflates normal lung regions, thus directing blood flow to diseased lung regions. In patients with air flow limitation and lung hyperinflation, the application of additional external PEEP to compensate ...
There’s effort involved to inflate them, but when the inflating pressure is released, the recoil of the elastic walls provides the pressure to deflate them.The lungs are suspended in the thoracic cavity at a slight negative pressure. When the diaphragm is lowered, that pressure becomes ...
lungs lack a surfactant chemical. Sur-factants lower the surface tension on the air side of the lung’s tiny air sacs – the alveoli – causing them to open up enough to exchange oxygen. Without sufficient surfactant, surface tension makes the alveoli harder to inflate, so the b...
Fish rise and sink in water primarily using a swim bladder, which they inflate or deflate with oxygen to adjust their buoyancy. The swim bladder's volume changes allow the fish to displace different amounts of water, balancing the forces of buoyancy and gravity. Some fish, like sharks and ...
inserted into one of your veins in order to deliver sedatives and pain medications. That way, you won’t feel any pain during your colonoscopy. You may feel some pressure as the colonoscope moves through your colon and as it’s used to inflate your colon to give your doctor a better ...
My friends decided it was time to let their son be alone for a night and said, "We're in" for the night out. CanvaOne of my other friends was horrified that this other couple would leave their son home alone at such a young age....
