The nervous system comprises the body's total response mechanism. It receives external information, sends that info to the brain for processing, and sends messages from the brain about appropriate response to the effector muscles and glands.

I'm not 100% sure, but i believe its considered the most complex because the nervous system includes over 1,000 tiny nerves running all throughout your body, sending and receiving signals from the brain, a constant course of "electric" activity. Just my guess.

It is considered as the complex system of the body because it has 2 big divisions the peripheral and the central nervous system the central nervous system takes charge of the complex brain functions, such as intelligence,memory,behavior and feelings.that is why.
