respiratory rate and tidal volume should be increased. so that the excess dead space can be can be outweighed. 4. (2pts) Briefly describe how the respiratory membrane works. What cell types and what forces allow the diffusion of gases across the respiratory membrane? It is through this mechanism that blood is oxygenated and carbon dioxide is removed from the body. In the respiratory membrane the alveolar and capillary walls meet, and gases move across the membranes with oxygen entering the blood stream and carbon dioxide exiting. It includes the alveolar epithelial cells as well as the pulmonary capillary endothelial cells. The force behind this is diffusion which is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. 5. (2pts) What are the respiratory centers within the central nervous system? Identify the stimulus that causes a response in each . The respiratory center is made up of three major respiratory groups of neurons , two in the medulla and one in the pons. In the medulla they are the dorsal respiratory group and the ventral respiratory group. In the pons, it is the pontine respiratory group. The medulla sends signals to the muscles involved in breathing, and the pons controls the rate of breathing. The chemoreceptors in the medulla and in the aortic and carotid bodies of the blood vessels detect changes in blood pH and signal the medulla to correct those changes. The apneustic center sends signals for inspiration for long and deep breaths. It controls the intensity of breathing and is inhibited by

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
