Cells, tissues, organs, and then organ systems.

The structures of the human body in order from least to most complex are cell, tissue, organ, and organ system.

Multicellular organisms have 5 levels of organization ranging from simplest to most complex...cells, tissues, organs, organ systems, organisms.
Species Genius Order Class Phylum Kingdom
The structures of the human body in order from least to most complex are cell, tissue, organ, and organ system.
Single cell paramesium would be the least complex then up through cells of the blood and brain onto multi cellular slugs. Once you get to levels of orgainisation that have speciallised cells for motion, digestion, vision etc then where the creature can live becomes a factor. What is called the 'tree of life' gives more detail but it is a long and increasingly complex ange of creatures involved
The classification levels from most broad to least broad are: Kingdom, Phylum, Class, Order, Family, Genus, Species
