Question
Blood flow velocity is slowest in because this is where is greatest. Select one: arterioles, resistance capillaries, resistance veins, cross-sectional area aorta, cross-sectional area capillaries, cross-sectional area which ONE of the following would NOT result in an increase in the movement of fluid out of capillaries? Select one: An increase in blood pressure within the capillary None of the above. A decrease in interstitial fluid pressure. A decrease in colloid osmotic pressure of the plasma. A decrease in the osmotic pressure of the interstitial fluid. Compared to sinoatrial cells, ventricular contractile cells will have: Select one: An action potential with a shorter duration A smaller amplitude action potential A slower conduction velocity A more negative resting membrane potential A slower depolarisation during the action potentialExplanation / Answer
1) capillaries and cross sectional area.
2) A decrease in the osmotic pressure of intestinal fluid.
3) A more negative resting membrane potential.
4) Ventricular end diastolic volume.
5) All of the above.
6) A-V valve closure, first heart sound, Ventricular systole.
7) 100ml
8) AV valves are closed and the semilunar values are open as blood is leaving the ventricle.
9) Causes bradycardia
10) All valves are never open normally simultaneously.
11) Sympathetic nerve activity.
12) Increase, vasoconstriction.
