Define: 1) Transportation 2) Control 3) Coordination.

Dear Student,
Control and coordination
Living organisms always interact with the external environment and accordingly respond to it. So the responses which a living organisms makes with respect to external stimuli are controlled and coordinated by different systems present in the organisms. For example, nervous system and endocrine system together controls as well as coordinate various functions in the body such as metabolism etc. 
 
All the body function are highly controlled and coordinated. Control is the power of regulation by which a process can be started, slowed down, maintained or stopped, while coordination is the the orderly working of all the body parts and process together to perform one or more activities properly.

Kindly post remaining query in next thread.

Regards
