Suppose the person exercises, so that tidal volume increases to 4000 mL, dead space increases to 300 mL due to dilation of the respiratory passageways, and respiratory rate increases to 24 breaths per minute.

- What mechanisms regulate ventilation at the onset of exerciseand then during exercise? What is the anaerobic threshold?arrow_forwardDuring normal quiet breathing: O only expiration requires muscle activation no muscles are involved in either inspiration or expiration Muscle contractions are needed for both inspiration and expiration muscle action is only required for inspiration, whereas expiration occurs due to passive elastic recoil of tissues that were stretched during inspiration The lungs stick to the wall of the thoracic cavity due to: negative intrapleural pressure in the pleural cavity and adhesion of fluid in the pleural cavity to the pleura. Adhesion junctions between the parietal and visceral pleura fibrous connective tissues between the visceral and parietal pleura Surfactant in the intrapleural spacearrow_forwardGive any three differences between External respiration and Internal respiration?arrow_forward
- The forces for resting expiration come from the elastic recoil of tissues and from surface tension. The lungs contain considerable elastic tissue, which stretches with lung expansion during inspiration. As the diaphragm and external intercostal muscles relax following inspiration, the elastic tissues cause the lungs to recoil and return to their original shapes. This pulls the visceral pleural membrane inward, and the parietal pleura and chest wall follow. Also, during inspiration the diaphragm compresses the abdominal organs beneath it. When the diaphragm relaxes, the abdominal organs spring back into their previous shapes, pushing the diaphragm upward(fig. 16.14a). At the same time, the surface tension that develops on the moist surfaces of the alveolar linings decreases the diameters of the alveoli. Together these factors increase intra-alveolar pressure about 1 mm Hg above atmospheric pressure, so that the air inside the lungs is forced out through respiratory passages with no…arrow_forwardName the vessels (in the correct sequence) that CO2 travels in during transport.
