About the Class
The transport system in animals is called the circulatory system. The materials are transported from one part of the body to another by a mass flow system which is the circulatory system. The animals, particularly the more advanced forms, have a higher metabolic rate. This means that they require more nutrients and oxygen at a faster rate. They also produce more wastes that have to be removed from the cells in less time. The circulatory system has to ensure that the materials reach all the cells of the body and in time. This system should also collect the materials from the cells and transport them wherever required. Thus, the movement of materials into and out of the system should be possible. The need to meet all these requirements has resulted in a mass flow system through blood vessels and body spaces.
