Coordlinahon- Process by which two or more organs interact oordination- Process b w and compliment the tunchon each other. Neural System Endocrine Sustem / By means % Hormones. whole target tissue responds eg hen you take insulin shots. v Fast and point to point. Slow and Dised By means ok electrical impulses Neurons Carries Hormones Response is limited and er Shorter Duralion er longer duration. eg.when you step on a pin.
