Question

humans are complex organisms. complex organisms are made of smaller parts organized in sets together to carry out the important functions of life. cells form tissues, tissues form organs, organs form organ systems, and organ systems work together to form the organism. the diagram shows the levels of organization in the human digestive system, where a cell of select organ systems in the human body. cell tissue organ organ system organism which model best represents how the human body is organized?

Explanation:

Human body organization follows a hierarchical, nested structure: cells form tissues, tissues form organs, organs form organ systems, and organ systems make up the whole organism. A concentric circle model best represents this nested, increasing complexity hierarchy, where each level is contained within the larger, more complex level above it.

Answer:

The concentric circle diagram (the second diagram from the top, with the smallest circle at the center labeled "cell", then "tissue", "organ", "organ system", and the largest circle "organism")
