Amino acids are the building blocks of cells. Cells are the
building blocks for tissues; cells specialize into specific types
of tissues. Tissues built of specialized cells form organs. Single
or multiple organs make organ systems. All of the organ systems
make up the organism, the human body in this case.
Cells are the smallest but most powerful unit in the body. Nutrients and oxygen pass through the cell membrane, producing energy and body heat. Cells have machinery to fight infection. Cells also reproduce to repair injuries or diseases, if they can.
Cells specialize into groups of tissues. Specialized tissues have usually one function.
Tissues are grouped by function into body organs. Organs are entirely specialized for a certain function.
Organs are grouped into organ systems. Each organ system has a separate function.
Organ Systems make up the body, or the organism.
