Web19 Dec 2024 · 1 When the diaphragm (rubber sheet) moves down, the volume inside the glass jar (thorax) increases. 2 This increase in volume causes a decrease in pressure. 3 The lungs (balloons) inflate as air enters until the pressures inside and outside are equal. How does breathing affect the volume of the thorax?

Web12 May 2024 · As the thoracic wall moves outward and the diaphragm descends, thoracic volume and therefore lung volume increases. More tension is generated in the stretching elastic tissue of the lungs as the lung expands—and just like stretching an elastic band, the recoil force increases, and the stretching lung now pulls back harder on the pleural space. Web16 Jun 2024 · Note that this does not occur when lying down, because in this position, gravity does not preferentially pull the bottom of the lung down. A physiological shunt can develop if there is infection or edema in the lung that obstructs an area. This will decrease ventilation but not affect perfusion; therefore, the V/Q ratio changes and gas exchange ...
WebExternal respiration is about the mechanics of breathing, getting oxygen into the lungs and regulating it in a way that ensures its diffusion into the blood.It is also about ensuring proper diffusion of CO 2 from the blood into the lungs, and its subsequent excretion into the atmosphere. Breathing mechanics include breathing rate, breathing depth (volume of air …
Web22 Apr 2024 · Answer: When, the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.
