The level of organization is matched as:

Cell - basic unit of structure and function of all  living things.

Tissue - group of cells that work together to perform  a common function

organ -group of tissues that work together to  perform a common function

organ system : group of organs that work together to  perform a common function

The organ system: It is the assembly of organs which combine to perform a same  functions for example urinary bladder, ureters, urethra and kidney makes excretory system or organ system of kidneys.
