The cellular level is the smallest level of the organization of the human body because cell is the smallest functional unit of the body having the different specified functions. As the humans are eukaryotic systems with multicellular structure they have the well defined cell in their structural organization having the nucleus and other constituents in specified way.

From cellular level we will go for the tissue level where group of cells are organized to for the tissue for a common function. The tissue may have two or more type of the cells also in their structural organization like connective tissue and nervous tissue with their characteristic function.

From the tissue level we will go for the organ level where different tissues make or constitute a specific organ for a specific function in the body like brain, kidney stomach and liver. From this level the complexity of the structural organization starts.

At the last on organizational level the different organs are highly organized to complete the human body to work together to accomplish the multiple functions of the living body and comprise various systems like respiratory system, nervous system, digestive system and reproductive system.

Thus the organizational level is very complex in the structure and the physiology.
