signals for inspiration for long and deep breaths. It controls the intensity of breathing and is inhibited by the stretch receptors of the pulmonary muscles at maximum depth of inspiration, or by signals from the pnuemotaxic center. The pnuemotaxic center sends signals to inhibit inspiration that allows it to finely control the respiratory rate. Its signals limit the activity of the phrenic nerve and inhibits the signals of the apneustic center. It decreases tidal volume.

6. (3pts) In pathologic conditions where the alveolar membrane is thickened there is little effect on the exchange of carbon dioxide, but oxygen diffusion is impaired. Based on your understanding of the respiratory membrane function, propose an explanation for this phenomenon. Solubility of carbon dioxide is higher compared to oxygen. Despite this fact, oxygen diffusion is more compared to carbon dioxide because of greater pressure difference across alveolar membrane and lesser molecular weight. When the alveolar membrane thickness is increased, distance molecules need to diffuse is increased and hence oxygen diffusion is impaired because of lesser solubility while carbon dioxide diffusion, because of greater solubility, remains almost unaffected. 7. (2pts) Why is alveolar ventilation rate a more important physiological measure of respiratory function than total air moved into the respiratory passages? Alveolar ventilation rate is a more important physiological measure of respiratory function than total air moved

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
