Human Body Organization and Systems

Mrs. Jacobson explains the levels of organization in the body, starting from cells, the basic unit of life, to tissues, organs, and organ systems, culminating in a complete organism. She uses examples like muscle cells and the heart to illustrate how these levels work together. The video also includes a practical example using her dog, Shadow, to demonstrate these concepts in a relatable way.
