Get Reading Activity: The Organization of Human Body

These parts are divided into levels of organization. There are five levels: cells, tissue, organs, organ systems, and organisms. All living things are made up of cells.

The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.

It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity, such as (from smallest to largest): chemicals, cells, tissues, organs, organ systems, and an organism.

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

Living organisms are made up of four levels of organization: cells, tissues, organs, and organ systems.

An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.

Summary. The human body is organized at different levels, starting with the cell. Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems.
