The bronchi are the airways that lead from the trachea into the lungs and then branch off into progressively smaller structures until they reach the alveoli, the tiny sacs that allow for the exchange of oxygen and carbon dioxide in the lungs. While the bronchi function primarily as passageways for air, they also play ...

WebThe lung epithelium is continuously subjected to biomechanical stimulation by breathing; mechanical stress and deformation influence biological function and signalling of alveolar epithelial cells [122]. Web7 mei 2024 · The lungs are the largest organs of the respiratory tract. They are suspended within the pleural cavity of the thorax. In Figure \(\PageIndex{5}\), you can see that each of the two lungs is divided into sections. These are called lobes, and they are separated from each other by connective tissues. The right lung is larger and contains three lobes.

WebSo, in healthy lungs, respiratory membrane is 0.5–1 micrometer thick. In lung fibrosis, on the other hand, the alveolar-capillary wall thickens and a thicker alveolo-capillary membrane reduces the rate of diffusion. Now, the gas exchange across the alveolo-capillary membrane happens according to what is known as Fick’s law. react typed jsWebAlthough significant strides in the understanding of pulmonary immunology have been made, much work remains to be done to comprehensively explain coordinated immune responses in the lung.
