Some systems are considered transport for the body because . The circulatory system helps blood flow through your body therefore it is transportation. The respiratory system helps you breath in good air and breath out bad air . It is considered transport because it's moving the air we breath. The digestive system moves the food into the stomach and breaks it down .
And the excretory system moves wastes out of the body.
