I think the answer you're looking for here is nervous tissue which carries action potentials, or nervous impulses, between the tissues and are central nervous system. However, from another point of view you could also consider the cardiovascular system as carrying hormonal messages throughout the body.

The lymphatic system is what carries the fats around in our bodies. Excess fat is stored in fat cells specialized for that function and are called adipose tissue.
Iron is a part of all cells and does many things in our bodies. For example, iron (as part of the protein hemoglobin) carries oxygen from our lungs throughout our bodies. Iron also helps muscles store and use oxygen.

Small spherical bodies made up of lymphatic tissue are called lymph nodes.
