This resource provides an introduction to the foundational concepts of anatomy and physiology, delineating their definitions and interrelationship. It covers the hierarchy of biological organization from the chemical to the organism level, detailing each stage with examples, particularly related to the heart. The document emphasizes how structural characteristics (anatomy) influence the functional capacities (physiology) of biological systems, particularly focusing on the heart. Additionally, it includes case studies, activities, and extension tasks designed to deepen understanding of the form-function connection in human biology.
