Increase in CO2 concentration

Increase in pH

|
Increase in nitric oxide

Explanation:
Detailed explanation-1: -For more than a century, it has been known that changes in pH are determinant of tone. Gaskell (34) demonstrated that acid solutions evoke vascular smooth muscle relax-ation and more recent studies have shown that reduction of blood pH increases blood flow (35).
Detailed explanation-2: -Dilation of arterioles causes a decrease in resistance, increasing blood flow to downstream capillaries and a smaller decrease in blood pressure.
Detailed explanation-3: -The correct answer is c. increased pressure of the blood entering the vessel. The blood pressure for the blood flow is created by the hydrostatic pressure of the blood vessels that helps to move the blood from the area of higher to lower pressure.
