Key features of a mass transport system:moving transport medium?
Mechanism for moving the transport medium through the vessels (the heart)
Key features of a mass transport system: unidirectional?
Mechanism to ensure mass flow is unidirectional- valves to prevent the backflow of blood
Key features of a mass transport system: controlling the flow?
Mechanism for controlling the flow to suit the changing needs of the organism (heart rate)
