Cardiovascular system
The main system that serves the needs of individual cells in multicellular organisms is the circulatory system. This is used to take waste away from individual cells and bring in new fuel such as proteins, glucose, and oxygen.
There are dozens of cellular 'transport' systems. Question needs focus, thanks.
Water is mainly needed for your cells and cells need water because: - (Intake of) water maintains the osmotic pressure inside a cell. - Water is used to dissolve most chemicals the cell needs to function (no fatty acids) - Water is used in transportation of food and waste.

It's simple really the reason why multi-cell beings need organs in the first place is because they have so many cells. The cells have needs that they cannot obtain alone and must rely on the cells to produce such. For example the Heart pumps the blood which brings oxygen to the cells. Its a much more complex system and therefor makes cells have certain tasks all of which are extremely important and ensures the survival of themselves and the other cells in the body. Single cell life on the other hand can just absorb what it needs through its surroundings.

The circulatory system pumps the blood which carries the nutrients that the cells needs. The circulatory system gets the nutrients from the digestive system.
They don't - everybody needs transportation.

Some of the functions of the United States Department of Transportation ( US DOT) are to ensure a fast, efficient, safe, accessible, and convenient transportation system that meets the needs of the nation.

no, Immune system is your body defender from bacteria. think of the Immune system as your body warrior, and the circulatory system you can think of it as your airport or transportation system were it takes your passengers (red blood cells, white blood cells, oxygen particles and carbon dioxide) to all different parts of your body however, when the oxygen goes in; it violates the laws (by becoming carbon dioxide) so the body needs to exile it by removing it out of the body and finds shelter in plants :) hope that helps :)
