Need for a transport system:

Transport system is essential to keep the cells alive and healthy
Failure of these transport systems would result in diseases
Cells require various substances, such as amino acids, fatty acids, vitamins and minerals. Transport system supplies them to the cells.
Cells also require water. It is not possible to supply water to all the cells. It is supplied to the cells by the transport system individually to every cell in the body.
The food we eat is digested and transported to all the parts of the body.
Oxygen is required, for the oxidation of food. Oxygen is taken into the lungs and from lungs it is supplied to every individual cell in the body. Carbon dioxide produced during the oxidation process in each cell should be collected and transported to the lungs.
Several waste materials are generated during the oxidation of food in the cells. Therefore, they are to be collected and transported to various sites in the body for disposal.
Hormones are produced by endocrine glands present at different locations in the body. They work at place other than the place where they are produced. Therefore they are to be transported.
