Quizplus · Accepted Answer

Arterioles are the most important vessels for controlling resistance to blood flow. They are able to alter their diameter in response to signals from the nervous system and chemical signals in order to adjust the amount of blood being delivered to a particular area of the body. This adjustment in diameter changes the resistance to blood flow and affects blood pressure.
