WebScar tissue in lungs → scar tissue is thicker and less elastic which means that: diffusion distance is increased so rate of diffusion is decreased. Faster ventilation rate to get enough oxygen into the blood and lungs. Lungs can expand and recoil less → Can’t hold as much air which means a reduced tidal volume and forced viral capacity WebThe information below was adapted from OpenStax Biology 39.2. The structure of any respiratory surface (lungs, gills, tracheae), maximizes its surface area to increase gas diffusion. Because of the enormous number of alveoli (approximately 300 million in each human lung), the surface area of the lung is very large (75 m 2). Web3) Ventilation of the lungs brings oxygen into the alveoli and removes carbon dioxide. The circulation of blood through capillaries is constantly bringing in blood with low oxygen. This maintains a steep concentration gradient across the alveolar wall for a faster rate of diffusion for oxygen and carbon dioxide. Answered by • Biology tutor. rules on rounding off numbers
