question 29 of 30
the endocrine system
a. speeds your body up when needed.
b. carries messages up your spinal cord.
c. releases hormones into your bloodstream.
d. slows your body down when needed.

Explanation:

The endocrine system consists of glands that secrete hormones directly into the bloodstream. Hormones regulate various body functions. Option A and D are more related to the sympathetic and parasympathetic nervous systems (though some hormones can have such effects, the core function is hormone release). Option B is related to the nervous system (spinal cord is part of the nervous system for message - carrying).

Answer:

C. releases hormones into your bloodstream.
