question 30 of 30
the endocrine system:

a. carries messages up your spinal cord.

b. speeds your body up when needed.

c. releases hormones into your bloodstream.

d. slows your body down when needed.

Explanation:

The endocrine system's main function is to secrete (release) hormones into the bloodstream. Option A describes the nervous system's spinal cord function. Options B and D relate to the sympathetic/parasympathetic nervous system (speeding/slowing the body), not the endocrine system's core role.

Answer:

C. releases hormones into your bloodstream.
