Exploring Levels of Organization in Biology

The video compares the construction of a city to the organization of the human body, starting from the smallest units, cells, which form tissues. Tissues then form organs, and organs work together in organ systems. Examples of cells, tissues, and organs are provided, along with a detailed explanation of the nervous, respiratory, and skeletal systems. The video concludes with a summary of the levels of organization: cells, tissues, organs, and organ systems.
