◻Arterioles dilate in response to epinephrine and norepinephrine. Precapillary sphincters dilate in response to muscle metabolites such as lactic acid,
CO_(2), and adenosine. Muscular contraction compresses the blood vessels. Precapillary sphincters constrict in response to muscle metabolites such as lactic acid,
CO_(2), and adenosine.
◻Blood is diverted from other organs such as the digestive tract and kidneys to meet the needs of the working muscles.
