Leaky Na+ channels in the cells of the SA Node do which of the following?
a-allow a slow repolarization which causes the delay in the AV Node
b-allow a slow depolarization which causes the atria to contract for a longer time and fill the ventricles more completely
c-allow a slow repolarization which brings the membrane potential back to a resting state
d-allow a slow depolarization that eventually reaches the threshold for voltage-gated Ca2+ channels

- An artificial heart works in closed loop by varying its pumping rate according to changes in signals from the recipient's nervous system. For feedback compensation design it is important to know the heart's open-loop transfer function. To identify this transfer function, an artificial heart is implanted in a calf while the main parts of the original heart are left in place. Then the atrial pumping rate in the original heart is measured while step input changes are effected on the artificial heart. It has been found that. in general, the obtained response closely resembles that of a second-order system. In one such experiment it was found that the step response has a %OS = 30% and a time of first peak 7, 127 sec (Nakamura, 2002). Find the corresponding transfer function. Aside from the corresponding transfer function, determine the following as well: delay time, rise time, settling time and steady state error if input is a step response. CO Marrow_forwardName three mechanisms that can increase cardiacoutput.arrow_forwardIn conditioned athletes, the resting Heart Rate is generally much lower than in non-athletes. Why? a-because long-term exercise reduces Cardiac Output at rest to conserve energy b-because athletes have a smaller Stroke Volume at rest, causing Heart Rate to decrease as well c-because long-term exercise leads to increased vagal tone which slows Heart Rate d-because athletes have stronger ventricles and therefore a larger Stroke Volume at rest, so they require fewer bpm to achieve the same Cardiac Outputarrow_forward
- Why do implantable defibrillators require far less power on their own than a pacemaker?arrow_forwardCritically ill patients in a cardiovascular intensive care unit must be intensely monitored for any number of conditions. One of these conditions is hypoperfusion, which is an overall decrease in blood flow throughout the body. Low stroke volume is one indicator of hypoperfusion. The pressure-volume (PV) graph below shows three possible loops for the heart. The control loop shows a healthy heart while the other two loops show reduced or increased preload (assuming that afterload and contractility remain fixed). 200 LV Pressure (mmHg) 100 Preload Control ↑ Preload 100 LV Volume (ml) (a) What is the stroke volume for the control patient? RK '15 200 (b) A healthy heart rate (HR) is measured as 80 beats per minute. What is the control patient's cardiac output CO?

Why is the cardiac action potential propagated more slowly in an AV node cell than in an atrial or ventricular myocyte?

- Which of the following statements best describes the differences in the regulation of cardiac and skeletal muscle contraction? The amount of contractile force actively generated by muscle cells is increased by stretch in skeletal muscle and decreased by stretch in cardiac muscle. Cardiac muscle is stimulated by motor neurons and skeletal muscle by neurones from the autonomic nervous system. Skeletal muscle contractile force is augmented by increasing the firing frequency of action potentials whereas cardiac muscle contractile force is enhanced by noradrenaline increasing calcium influx through ion channels. Ryanodine receptors in skeletal muscle are opened by a mechanism that requires calcium influx whereas in cardiac muscle membrane depolarisation alone without calcium influx is sufficient to open ryanodine receptors.arrow_forwardThe aorta is the principal blood vessel through which blood leaves the heart in order to circulate around the body. (a) Calculate the average speed of the blood in the aorta if the flow rate is 5.0 L/min. The aorta has a radius of 10 mm. (b) Blood also flows through smaller blood vessels known as capillaries. When the rate of blood flow in the aorta is 5.0 L/min, the speed of blood in the capillaries is about 0.33 mm/s. Given that the average diameter of a capillary is 8.0 μm (1 μm = 1 X 10 –6 m), calculate the number of capillaries in the blood circulatory system.arrow_forwarda) List at least five things that a circulatory system does to help the body cells. Which of these is most important? b) Name some animals with an “open circ system” ; know how it works with some vessels, heart/pumps and hemolympth blood-like fluid c) what are the general differences between veins, capillaries and arteries? What do we call very tiny arteries? Very tiny veins?arrow_forward
