Brain, spinal cord, nerves
The brain controls thought, behavior, emotion, memory, and basic life functions. The brain is also the origin of control over body movement. The spinal cord connects the peripheral nervous system (PNS) to the brain; nerve impulses reaching the spinal cord through sensory neurons are transmitted up into the brain. Nerves primarily involve control and coordination of all parts of the body.
The nervous system interacts with every other organ system. For example the hypothalamus in the brain controls the pituitary gland and tells it when to produce hormones, this shows that the nervous system interacts with the endocrine system.

What diagram are you talking about
Answer:
C. as nonspecific defenses, because they bar or stop infections without discriminating pathogens from other agents
Explanation:
The skin, tears and stomach acid are nonspecific defenses and they are some of the examples of the body's first line of defense. Nonspecific defenses are made up of interferons, chemical barriers (e.g. tears and stomach acid), inflammation and physical barrier (e.g. skin).
These nonspecific defenses defend the body from pathogens through their chemical contents in the body fluid or the tissue.
For example, Stomach acid is made of hydrochloric acid (HCl), HCl is potent enough to destroy pathogens that make its way into the stomach through food; this kind of barrier is a chemical barrier.
So also, the skin is a physical barrier which serve as a defense against pathogens.
