Quizplus · Accepted Answer

The endocrine system is responsible for releasing hormones into the bloodstream to carry out long-term communication within the body. Neurotransmitters are released by the nervous system and act over short distances at synapses. Neuromodulators are also released by the nervous system and modify the activity of neurons, but they do not enter the bloodstream.
