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 organizationstructure- functionhomeostaticregulationRenal System
