The influence of blood vessel diameter on peripheral resistance is The only factor that influences resistance Significant

Question

The influence of blood vessel diameter on peripheral resistance is The only factor that influences resistance Significant because resistance is inversely proportional to the fourth power of the vessel radius Insignificant because vessel diameter does not vary Significant because resistance is directly proportional to blood vessel diameter 6 1 point Factors that aid venous return include all except 7 1 point Which of the following statements is correct 0000 Urinary output Pressure changes in the thorax Activity of skeletal muscles Venous valves 000 Hydrostatic pressure will drop as blood moves away from the arteriole end of the capillary bed Hydrostatic pressure will rise as blood moves away from the arteriole end of the capillary bed Hydrostatic pressure will remain constant throughout the capillary bed Osmotic pressure will be lower in the arteriole end of the capillary bed compared to the 8 1 point The velocity and pressure of blood is slowest and lowest in the capillary beds Which of the following is not an accurate description of the I slow low pressure blood in the capillary beds Lower pressure reduces the chance of injury to delicate capillary vessels Lower pressure on the venous end of the capillary bed allows for greater reabsorption of fluid back to the plasma bed helps to increase pressure in the venous circulation
