1 Renal System Introduction Nephron structure and functions Filtration, reabsorption, secretion Clearance (inulin, G, PAH, creatinin) Micturition, control of bladder, input / output sphincters 14 The goal of these lectures is to discuss basic renal physiology. This lecture will introduce the topic and discuss the concept of renal clearance. 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
