Check all that are true of the endocrine system. it communicates using neurotransmitters. it communicates using hormones secreted into the bloodstream. it causes metabolic activity changes in its target cells. it typically has localized, specific effects in the body. its effects last from minutes to weeks. its effects may continue after the stimulus is removed.
