Introduction to Anatomy & Physiology

Anatomy vs. Physiology00:00:00

This section defines anatomy as the study of body structures and their physical shapes, and physiology as the study of how those structures function. The relationship is explained through the analogy of a car: anatomy constitutes the parts, while physiology is how those parts work together to create movement.

Levels of Organization00:01:43

The human body is described as a complex organism organized into hierarchical levels: starting from atoms, moving to molecules, macromolecules, organelles, cells, tissues, organs, organ systems, and finally the complete organism.

Characteristics of Life00:02:38

This section outlines the essential characteristics that define life, including organization, metabolism (catabolism and anabolism), responsiveness to stimuli, growth, development, and reproduction.
