Upon inhalation,the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs. Does the thoracic cavity size v...
(a) diminishes the volume of the thoracic cavity (b) increases the volume of the thoracic cavity (c) pushes the rib cage downward (d) causes external intercostal muscles to relax (e) decreases lung capacity. If the lungs were to lose their elastic recoil, how would you ...
To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs. How does the diaphragm moves during inhalation? When the lungs inhale, the diaphragm contracts and pulls downward. At the ...
The significance and alarming levels of the measured values become evident upon reviewing the inhalation and oral toxicity (the two possible exposure routes related to a mask use) of Zn, Cu, Pb and Sb. Specifically, upon inhalation, Sb in amounts greater than 8.87 mg m−3, can cause pneu...
Breath-holding - A Strategy in Enhancing Drug Delivery to the Lungs: A Review After inhalation of pharmaceutical aerosols, holding of breath prior to exhalation is one of the simpler inhaler techniques when using pressurized metered-dose inhalers and dry powder inhalers. Many benefits are offered ...

The toxic effects caused by aerosols through inhalation exposure are affected not only by the inherent toxicity caused by differences in chemical composition and the particles’ size, surface area, and shape, but also by the accumulation of effective dose that penetrates deep into the lungs, such ...

During expiration, the diaphragm and intercostals relax, causing the thorax and lungs to recoil. The air pressure within the lungs increases to above the pressure
