Exploring the Levels of Biological Organization

The video explains the levels of organization in the human body using a city-building analogy. It starts with cells, the smallest living units, which combine to form tissues. Tissues then form organs, and organs work together to create organ systems. Examples include brain cells forming brain tissue, which becomes part of the nervous system. The video concludes by summarizing these levels: cells, tissues, organs, and organ systems.
