Why do large organisms need a mass transport system
They have a smaller SA so we cannot rely on substances diffusing as the process will take longer. They need a transport system to transport vital susbstances rapidly to all parts of the body. They are also more active-increases need for TS with pump

What are the features of a transport system
It has a transport medium in which substances can be carried by transport medium. Has a form of mass transport to carry the transport medium to the parts of the body. A mechanism for moving the transport medium which requires a pressure difference

Why do organisms need a double circulatory system
Organisms need a double circulatory system as the blood from the lungs is flowing at a lower pressure thereofre it will take longer for all the blood to reach the extremities of the body. Thus it needs to go to the heart to get a boost of pressure.
