How do nervous and endocrine systems work together?
ludmilkaskok [199]

Answer:

5. : Produces the body's major metabolic hormones.

Explanation:

The endocrine system is made up of several glands. The main ones are pituitary, thyroid, adrenal, pancreas, ovaries and testes. They secrete the body's main hormones, which are carried by the blood throughout the body, under the command of the nervous system, and act on specific cells. This, in turn, is formed by the central nervous system (CNS), the peripheral nervous system (PNS) and the autonomic nervous system (ANS). The basic units are nerve cells, which transmit electrical impulses accurately and quickly.

Thus, we can state that the production of the body's major metabolic hormones represents the way the nervous and endocrine systems work together.
