Webb4 feb. 2024 · Surface tension is the force of attraction between liquid molecules at the liquid-gas interface which tends to minimise surface area. The relationship of this force to sphere size is described by the Law of Laplace. Smaller partially deflated alveoli will have lower compliance and higher Laplace pressure at any given surface tension. With lung … WebbThe most readily observable component of respiration involves the act of breathing, “during which the lungs are provided with air through inhaling and CO 2 is removed through exhalation.” 2 This process of moving air into and out of the lungs is known as ventilation. 1 While it may seem a simplistic process, the ability of air to flow into and out of the … recording karaoke machinesWebbDuring inspiration, alveoli expand passively in response to an increased transmural pressure gradient; during quiet expiration the elastic recoil of the alveoli returns them to their original volume.
