When you exercise, your heart speeds up, and a greater volume of blood is pumped around the body to meet demands. Both heart rate and stroke volume are affected by changes in blood gases, blood pressure, temperature and movement. Make reference to the following to help structure your answer: Inputs: Chemoreceptors Stretch receptors Thermoreceptors Pressure receptors How the information is processed by the brain Effectors – what nerves regulate heart rate in response to changes in each direction. Explain this concept in no more than 300 words. You must make reference to the nervous system in the control of these events.

Consider the equation cardiac output (CO) = stroke volume (SV) X heart rate Which of the following changes would increase cardiac output? Group of answer choices An increase in afterload An increase in EDV A decrease in ventricle contractility An increase in parasympathetic system stimulation of the SA node
Only one is correct Contraction of cardiac muscle is initiated during which phase of the fast action potential? What ion mediates this effect? A. Phase 0 due to Ca++ entry B. Phase 1 due to Na+ entry and K+ exit C. Phase 2 due to Ca++ entry D. Phase 4 due to K+ exit Group of answer choices Phase 2 due to Ca++ entry Phase 1 due to Na+ entry and K+ exit Phase 0 due to Ca++ entry Phase 4 due to K+ exit
In response to a severe hemorrhage, blood pressure lowers, the heart rate increases dramatically, and the stroke volume lowers. If low blood pressure activates a reflex that increases sympathetic stimulation of the heart, why is the stroke volume low?
In your study of neuron physiology, you learned that depolarization is dependent on the sodium entry (influx), and repolarization contingent on the potassium exit (efflux.) Compare the action potential in the heart’s intrinsic conduction and contractile cells, then explain why the electrocardiogram has different parts (P, QRS complex, and T wave.)?
Which of the following rows describes the change in heart rate, blood flow to skin, and glucose storage that would be expected to occur immediately following stimulation of the parasympathetic nervous system? Select one: a. Heart Rate Blood Flow to Skin Glucose Storage Increased Increased Decreased b. Heart Rate Blood Flow to Skin Glucose Storage Decreased Decreased Increased c. Heart Rate Blood Flow to Skin Glucose Storage Decreased Decreased Decreased d. Heart Rate Blood Flow to Skin Glucose Storage Increased Increased Increased
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.
In 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 Output
Sympathetic stimulation increases the phosphorylation of the Ca2+ATPase in the sarcoplasmic reticulum. What effect does this have on cardiac function? It increases the rate of diastole It decreases the stretch of the ventricles The rate of systole decreases
What happens to the pulse rate when activities demand more body movements? Explain. Give 2 systems that are directly affected whenever pulse rate increases? Why?
Predict the effects of a drug that blocks the sympathetic nervous system on blood pressure and heart rate. How would this drug affect heart rate, stroke volume and peripheral resistance?
What is the function of the pulmonary circulation In a resting state, explain what happened to the heart rate when the stroke volume decreased. Why does this occur? DescribetheFlank-Starlinglawintheheart. Compare the structural features of the different chambers and valves of the heart and how this relates to their function. Explain the flow of the blood as it passes through the heart. Describe how the heart alters stroke volume under sympathetic stimulation. please answer the queations into 2 paragraphs. thanks.
Diagram electrical conduction of the heart and discuss each component (SA node, AV node, etc). How does this dictate the fluidity of heart contraction? Why does the SA always start the conduction? What is the inherent rate of depolarization of the SA node (this means that if the nervous system was shut off what would resting bpm be)? If it is damaged what happens to the electrical conduction system?
