Overview

Understanding how the body works is vital for effectively treating patients. This knowledge is essential for advancing medical science, developing new treatments, and improving health outcomes. 

In this foundational HMX course, you will learn essential principles underlying how the human body functions. Through engaging, online lessons, you will gain an understanding of how this knowledge comes into play in real-world scenarios and in clinical settings from the intensive care unit to the cardiac catheterization lab.

Learning Objectives

  • Understand how the body reacts to stimuli to maintain steady-state conditions
  • Learn fundamental concepts like partial pressure, flow through tubes, compliance, supply and demand, and acid-base balance and how they relate to the working of biological systems
  • See how basic principles apply in real world and clinical settings

Participant Types

Pre-med students; Current medical students; Health care professionals working in R&D, product management and strategy, sales, and marketing

About the Course

HMX online courses bring complex material to life through engaging biomedical visualizations, clinical applications, and true-to-life scenarios paired with lectures from Harvard Medical School faculty and leading experts. 

Who Should Apply

This fundamentals course is appropriate for pre-med and current medical students interested in building their foundational knowledge of medical science, as well as professionals in health care and related fields who need a fundamental understanding of physiology – including those working in R&D, product management, strategy, sales, marketing, and other roles. 

Course Format

Most people can expect to spend around 40-60 hours total, but this depends on your baseline knowledge, how carefully you take notes, and how seriously you take the assessments. Lessons from the courses are released weekly and remain available until the courses end. The course wraps up with a final exam administered the final two days of the session.

HMX Faculty Perspectives

Why do you think it’s important for health care professionals to learn physiology?

"Physiology is truly the science of how the body works at a macro level. It helps us understand how all the organ systems are integrated and, when we are healthy, are seamlessly monitoring and responding to multiple unconscious inputs every moment of the day and night to keep us functioning well. It is also the foundation for studying and making sense of the impact of disease states, which invariably alter the normal physiology and lead to symptoms."  -Richard M. Schwartzstein, MD
