1 Renal System Regulation of H and Ca ions Hydrogen ions and homeostatic control, integration Metabolic and respiratory acidosis / alkalosis, integration Effectors for Ca homeostasis, sites and hormonal control Calcium related metabolic bone diseases, integration Hormonal and neural control of renal function 17 The goal of these lectures is to discuss basic renal physiology. This lecture will present the regulation of H and Ca ions as well as discuss the hormonal and neural regulation of renal function. The sections for this lecture are: 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 levels of organization structure - function homeostatic regulation Renal System

2 error signal amplification effectors mechanism effect Homeostasis, or constancy of the internal environment, is needed for chemical reactions underlying life to occur. It is maintained, predominantly, through negative feedback mechanisms what it actually is (info from feedback), is compared with what it should be (info from set-point) in a … comparator / integrator integrators compare what it should be with what it actually is and generate an error signal S ± E Renal System integrators compare what it should be with what it actually is and generate an error signal central integration center afferent efferent negative feedback signal Homeostatic Control effector S ± E Renal System
