1 Review for test #2 20 Life is a series of chemical reactions occurring in compartmentalized environments. The main purpose of life is to keep itself alive Physiology, the study of how life works, is based on the simultaneous occurrence of the following three concepts: levels of organization structure / function relationship homeostatic regulation This review only include the new material for the second test (from the cardiovascular lectures to the kidney lectures). It will highlight the main topics having in mind the test questions you will see on Wednesday. Remember all tests are cumulative. Review of cardiovascular lectures By the time you have f nished with the CV section , and as a way to test your knowledge of the subject, you should be able to provide a good answer to the following essay question: Name and describe four characteristics of cardiocytes not present in skeletal muscle cells, indicate the underlying mechanism for each one of them, and their physiological importance. Make sure to use in your description at least once, and in the proper context, each one of the following terms: heart rate, stroke volume, cardiac output, peripheral resistance, intrinsic control of CO, extrinsic control of CO, baroreceptor mechanism. Make sure to relate your description of these physiological events to at least one aspect of their structural-function relationship, indicating its levels of organization and provide an outline of a homeostatic control mechanism involved in these cardiovascular events.
