A and B are the two systems of control and coordination in the human body. The messages in system A are trasmitted in the form of chemical substances C which travel comparatively slowly through the blood stream. The substances C are made in tissues D present in the head and trunk of human body.

(f) State whether system A controls the working of system B or system B controls the working of system A.
