How are the cells in one system different from cells in other systems?

Cells are the smallest functional units of life. Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. The body has levels of organization that build on each other.
