Neural System The neural system coordinates and integrates functions as well as metabolic and homeostatic activities in all the organs. Coordination is the process through which two or more organs interact and complement the functions of one anothe For example, the functions of muscles, lungs, kidneys, heart, blood vessels and other organs are coordinated when we do physical exercises. . In human body the neural system and the endocrine system jointly coordinate and integrate all the activities of the organs so that they function in a synchronized fashion
The endocrine system provides chemical integration through hormones. The neural system provides an organized network of point to point connections for a quick coordination The neural system of all animals is composed of highlyv specialized cells called neurons which can detect,receive and transmi diffent kinds of stimuli. The neural organization is very simple in lower invertebrates. The neural system is better organized in insects, where a brain is present along with a number of ganglia and neural tissues .The vertebrate have a more developed neural system.
