Question
Chapter 42.2, Problem 3CC
Summary Introduction
To explain: The changes in functions of heart after regular exercise for several months.
Concept introduction:
Stroke volume means for each heart beat, the volume of blood is pumped out by each ventricle. The volume of blood pumped out through each ventricle by the heart per minute is the cardiac output. The cardiac output increases the active state and decreases in resting condition. The body has the ability to alter the heart rate and stroke volume.

Students have asked these similar questions
If you were sitting quietly in a chair, the time between each of your heart beats would be exactly the same.
T or False?
Days with low heart rate variability indicate that your nervous system is relaxed and ready to handle new challenges.
True or False?
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
[|q]. Toxt
Detail the control of heart rate. Include: resting values, inherent values, how the ANS modulates, factors that affect heart rate, etc.?

- 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_forward1)In the regulation of heart rate, which of the following is the proper stimulus? Group of answer choices -Change in mean arterial pressure -mean arterial pressure -change in heart rate -heart rate 2) If a stimulus is a decrease in mean arterial pressure (MAP), what must be the response if using the baroreceptor reflex? Group of answer choices -Increase in heart rate -Decrease in heart rate -Increase in MAP -Decrease in MAP 3)The brainstem acts as the integrating center for the baroreceptor and chemoreceptor reflexes.
