USMLE Step 1 Lecture Notes 2021: Physiology

A comprehensive overview of human physiology designed for students preparing for the USMLE Step 1 examination. The text focuses heavily on fluid dynamics, explaining how water and solutes distribute between the intracellular and extracellular compartments through the process of osmosis. Detailed Darrow-Yannet diagrams are utilized to illustrate how various clinical conditions, such as dehydration, hemorrhage, or salt ingestion, impact body osmolality and volume. Additionally, the source outlines the fundamental principles of excitable tissues, including the electrochemical gradients and membrane potentials that govern nerve and muscle function. Beyond these core concepts, the material serves as a roadmap for studying complex systems such as cardiovascular, renal, respiratory, and endocrine physiology. Practical tools, including basic metabolic profile reference ranges and the formula for calculating the osmolar gap, are provided to aid in clinical diagnosis.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/medicine_made_simpleProduced by:https://www.podcaistudio.com/
