The resistance of the blood vessels to blood flow through them is inversely related to what factor? The vessel length The volume of blood The viscosity of blood The pressure gradient across the vessel The vessel radius

Which of the following has the greatest effect on peripheral resistance?Question 14Select one:A.blood vessel diameterB.viscosityC.blood vessel lengthD.Viscosity, blood vessel length and blood vessel diameter affect peripheral resistance equally.

Which of the following blood vessels have highest resistance to blood flow?Multiple ChoiceMuscular arteries and large veinsElastic arteries and muscular arteriesArterioles and capillariesLarge veins and venulesElastic arteries, muscular arteries, and large veins

Select the correct statement about blood flow. It is greatest where resistance is highest. Blood flow through the entire vascular system is equivalent to cardiac output. It is measured in mm Hg. It is relatively constant through all body organs. It reduces significantly with age.

What formula best describes the relationship between the factors that determine blood pressure?Multiple choice question.cardiac output - peripheral resistancecardiac output x peripheral resistancecardiac output + peripheral resistancecardiac output / peripheral resistance

Q1. Name one (1) way your body can alter systemic vascular resistance (1 marks) and statehow this change would affect blood pressure by referring to the blood pressure equation
