Coordination: (L. co-joint, ordinates-regulated) is orderly or harmonious working of different but inter-related parts so as to perform one or more activities very smoothly.
Need for control and coordination in an organism:
The body of a multicellular organism consists of a number of components and sub-components; each specialized to perform a particular function. However, all the components are not required to function all the time at the same speed. A system of
controls is required to function all the time at the same speed. A system of controls is required to allow them to perform or not to perform, slow down or speed up their working. Further, most activities require the simultaneous or sequential functioning of a number of parts, stopping some and stimulation others. During feeding, eyes locate the food, nose registers its smell, hands pick up the food and take it to mouth, mouth opens to receive the food, teeth and muscles take part in its mastication and saliva
moistens it. Tongue perceives its taste. It moves the food below the teeth. Later it pushes the crushed food into pharynx. All this is possible only through a system of coordination.
