Cardiovascular System Quiz Item 2 Part A During exercise, our vessels constrict and vessel radius decreases. What impact does a decreased vessel radius have on blood flow? Blood flow increases Blood flow remains the same Blood flow decreases Vessel radius has no impact on blood flow
Complete the following statement. Choose all that apply. Resistance ___________________. Group of answer choices is due to friction between the moving blood and the stationary vessel wall. is doubled when the radius of a vessel is doubled. increases when the radius of the vessel increases. increases when blood pressure increases. increases when viscosity increases.
