Hierarchy of Biological Organization

The video lesson introduces the organization of the human body, comparing it to a city's structure. It covers the hierarchy from cells to organisms, providing examples of tissues, organs, and systems. Activities include matching keywords, completing tables, and understanding body responses to stimuli. The lesson concludes with optional tasks for further exploration.
