WebAn important characteristic of all tissues is the ability to “locally” control blood flow by regulating arteriolar resistance. Tissues utilize two methods of local control, myogenic and paracrine regulation. Myogenic regulation occurs because of the intrinsic property of smooth muscle cells to contract in response to stretch.
