Cells to Organ Systems

Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism

If your child was asked to explain how the body is built up from the smallest parts to the whole, could they describe the levels from individual cells all the way up to organ systems — with a real example at each level?

Builds on
Plant Cells vs Animal Cellsages 11–12The cell-to-organism hierarchy builds on understanding that different cell types exist
Cells to Organ Systemsthis skill · ages 11–12
Unlocks
Digestion & Enzymesages 11–13The digestive system is an organ system — the hierarchy concept gives the structural framework
The Human Skeletonages 11–13The skeleton is an organ system — understanding this level of organisation gives context
Gas Exchange & Breathingages 12–13The gas exchange system is an organ system — hierarchy concept provides structural context
Pathogens & the Immune Systemages 12–14The immune response involves specialised cells within organ systems (blood, lymph nodes)
