Organ systems work together
to carry out life activities.
We will study four organ
systems: the digestive,
respiratory, circulatory, and
excretory systems.
Digestive – breaks down food
into nutrients
Respiratory – brings oxygen
into the lungs
Circulatory – carries oxygen
from lungs to
cells in the body
Excretory – removes wastes
from the body
These organ systems are
called transport systems,
because they transport
(move) things throughout
the body.
Digestive System –
Transports food & nutrients
Respiratory System –
Transports oxygen
Circulatory System –
Transports nutrients,
oxygen, and wastes
Excretory System –
Transports wastes such as
carbon dioxide and sweat
