D Question 14 1 pts Consider all the blood vessels in the vasculature. Which ONE of the following statements is TRUE about blood vessels? All blood vessels have smooth muscle and are innervated by sympathetic nerves Blood is equally distributed between the arterial and the venous systems. In the capillaries, the cross-sectional area is inversely proportional to the velocity of blood flow. Question 15 1 pts There are drugs that can increase the sensitivity of Ca2+ binding to increase contractility. Which ONE of the following do these drugs likely affect? Select the best answer. O Troponin OCa2+ ATPase Na+/Ca2+ Exchanger Question 18 1 pts Given: Heart Rate = 70 bpm, End Diastolic Volume (EDV) – 120 mL, End Systolic Volume (ESV) = 60 ml. Cardiac output falls in which of the following ranges? (Watch the units! 1000ml-11) 4,0-4,5 L/min 8.0-3.5 L/min O 12.0-12.5 L/min D Question 19 1 pts When Ca2+ is released from troponin, what is happening at the level of the whole heart? Systole Diastole Isovolumetric contraction Question 20 1 pts Given: Systolic Pressure = 130 mmHg, Diastolic Pressure = 95 mmHg. Mean arterial pressure falls in which of the following ranges? 140-150 mm 100-110 mmHg 120-130 mmHg
