homeostasis
You can think of the body as having five levels of organization: cells, tissues, organs, organ systems, and the whole organism itself. The different systems of the human body work together to maintain homeostasis.
Organism (human)
Cells (cardiac muscle cells)
Tissue (cardiac muscle) Organ (heart) Organ system (circulatory
