What is the largest unit in the human body?
The levels of organization in the human body consist of cells, tissues, organs, organ systems and finally the organism. The smallest unit of organization is the cell. The next largest unit is tissue; then organs, then the organ system. Finally the organism, is the largest unit of organization.
What is the largest structural level?
organism level
The organism level is the highest level of organization. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life.

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.
Is the smallest unit of human body?
The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life.
What are the structural levels of the human body?
Life processes of the human body are maintained at several levels of structural organization. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels.

Which is the smallest unit in the human body?
Levels of Structural Organization in the human body. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. The smallest unit of any of these pure substances (elements) is an atom.
