Duration of the online course: 15 hours and 19 minutes
Build a clear, practical understanding of how the human body is structured and how it functions, from the microscopic level of cells to the coordinated work of major organ systems. This free online course in anatomy and physiology connects terminology with real biological purpose, helping you read health-related information with confidence, speak the language used in clinical and academic settings, and develop a foundation for further study in health sciences.
You will strengthen core scientific thinking by linking anatomy to physiology: what a structure is, where it is found, and why it behaves the way it does. Along the way, you will revisit essential concepts such as cellular organization, membranes and transport, basic chemistry in living systems, and the way tissues form the building blocks of organs. The course then expands into integrated body systems, showing how movement, sensation, and regulation depend on coordinated mechanisms rather than isolated facts.
As you progress, you will explore key physiological themes such as muscle contraction and control, skin as a protective and regulatory barrier, bone types and joint function, and the nervous system’s role in processing sensory input and directing responses. You will also connect communication within the body to bigger regulatory pathways, including endocrine signaling and the autonomic nervous system, emphasizing how balance is maintained through feedback and control. Each segment is designed to turn complex ideas into a coherent mental model you can apply to new scenarios.
The course also highlights transport and exchange systems that keep tissues supplied and stable. You will relate blood components to oxygen delivery, examine how the heart and vessels ensure one-way flow and efficient distribution, and see why capillary exchange matters for nutrient delivery and waste removal. From there, you will connect immune support and fluid balance to the lymphatic system, and trace how respiration and digestion contribute to homeostasis through gas exchange and nutrient absorption.
To reinforce learning, practice questions follow key lessons so you can check comprehension and improve recall under exam-style conditions. Whether you are preparing for a health program, returning to study after time away, or simply want a structured way to understand your body, this course offers an accessible path to stronger fundamentals and a more confident grasp of physiology.
