Besides heart rate, name another factor that is also controlled by the sympathetic nervous system to affect cardiac output. Briefly explain why
Homework Answers
Stroke Volume
- Cardiac output = stroke volume × heart rate
- Stroke volume is amount of blood pumped by heart in 1 beat
- Sympathetic system increases force of contractility of cardiac muscle therefore more force is generated and more blood is pumped out. This increases stroke volume
- This increase in stroke volume lead to increase in cardiac output
Feel free to comment if you have any problem in understanding this answer.

1. When is the parasympathetic nervous system generally active? When is the sympathetic nervous system generally active? 2. Briefly summarize the functions and actions of the parasympathetic and sympathetic nervous systems. 3. Speculate why the autonomic nervous system has ganglia. 4.Consider a reason why the neurotransmitter of the parasympatic postganglionic neurons is different than of the sympathetic postganglionic neurons.
Control of the heart rate and force of contraction are controlled by the [ Select] nervous...
Control of the heart rate and force of contraction are controlled by the [ Select] nervous system, where the [ Select] nervous system, through influence of epinephrine and norepinephrine from the adrenal medulla, increases the heart rate, while the [Select] nervous system, through the vagus nerve, decreases the heart rate. Increase in heart rate above 100 per minute is known as [Select] , while a decrease in heart rate below 60 per minute is known as (Select

Explain how the sympathetic nervous system acts to directly regulate stroke volume. Include a detailed description of the mechanism (include the target cells, the proteins, signaling molecules, ions, and changes in membrane potential where appropriate). What effect does this have on cardiac output. This will take about half a page to describe. Discuss venous return. Be sure: to define venous return and explain the importance of venous return to cardiac output. What determines venous return? Discuss each way that venous...
