Identifying cells, tissues,
organs, and organ systems,
Cells
 A structural unit of all living things. The
smallest unit classified as an living
organism.
Tissues
 Tissues are an
ensemble of cells,
they are not the same

carbohydrates into smaller molecules,
which can then be absorbed along
with vitamins and minerals
Respiratory
 Absorbs oxygen from the air and
excretes the waste product carbon
dioxide to the air.
Circulatory system
 distributes nutrients and oxygen to all
body cells plus hormones to target
cells, carries waste products to the
organs of excretion (kidneys, lungs),
toxins to the liver for detoxification
and also helps fight infections through
its white blood cells

 Regulate hydration of the body.
 Maintain acid-base balance of the body.
 Maintain blood pressure.
Nervous System
 To provide communication in the body,
sensations, thoughts, emotions, memories
and controls your reactions.
How do the organ systems work
together?
 distributes the above nutrients and oxygen
to all body cells plus hormones to target
cells, carries waste products to the organs
of excretion (kidneys, lungs), toxins to the
liver for detoxification and also helps fight
infections through its white blood cells
