An organ system is a group of organs that work together to

perform one or more functions in the body.

how many organ systems are there in the body

eleven

On a fundamental level, the body is organized from

the subatomic level all the way to the full organism

Atoms mark the

first level of organization

Multiple atoms can combine to form

molecules

Molecules then form structures called

organelles

organelles, which are the primary

working parts of all cells

Cells are the

structural unit of life of which all living things are composed. Single cell organisms only contain one cell

Muscles tissue

forms the structures that allow locomotion

Nervous tissue

forms the structures that allow communication between different organ systems to provide the stimulus for effects to occur

Epithelial tissue

covers the surfaces of the body (inside and out) which provides protection, absorption, secretion, and sensation

Connective tissue

tissue that connects, supports, or separates other tissues (e.g. cartilage, fatty tissue, elastic tissue, blood, bone, etc)

Groups of organs work together to form

organ systems

Grouping all the organ systems together makes the

full organism
