Introduction to Fields, Forces, and Flows in Biological Systems

How do biological molecules navigate complex cellular environments, and how do physical forces shape living tissues? To truly understand biology and bioengineering, you must grasp the underlying physical principles of transport, electrical fields, and fluid flows that govern living systems. This text-based course guides you through the fundamental engineering and biophysical concepts that dictate how molecules, cells, and tissues function. You will transition from a qualitative understanding of biology to a quantitative appreciation of the physical laws that drive biological processes, preparing you to analyze transport phenomena and mechanical forces in living systems. What you'll learn: - Understand the core terminology and physical principles of chemical gradients, diffusion, and active transport. - Analyze electrical interactions, membrane potentials, and electrochemical fields in cellular environments. - Practice modeling fluid flow and mechanical forces within microvascular systems and biological tissues. - Apply conservation laws to solve transport problems at the molecular and cellular scale. - Evaluate how physical fields and forces influence modern bioengineering applications and tissue engineering design. This course begins with essential foundational definitions, thermodynamic concepts, and transport terminology before moving step-by-step into fluid mechanics, electrical fields, and biological flux. You will explore realistic scenarios through clear explanations, conceptual breakdowns, and practical text-based exercises. This course is designed for beginners, aspiring bioengineers, and life science students looking for a solid introduction to biophysics without requiring advanced engineering prerequisites.
