What else can I help you with?
Which of the following would cause the greatest increase in cardiac output?
Increased heart rate and increased stroke volume
How does crank angle effect volume of cylinder?
The crank angle would change the stroke. The stroke would change the volume.
Would an increase in contractility cause an increase to cardiac output?
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
What happen ia a cardiac output of 5250 ml per minute with 75 heart beats the stroke volume is?
To calculate stroke volume, you can use the formula: Stroke Volume = Cardiac Output / Heart Rate. Given a cardiac output of 5250 ml per minute and a heart rate of 75 beats per minute, the stroke volume would be 5250 ml/min ÷ 75 beats/min = 70 ml per beat. Therefore, the stroke volume is 70 ml.
In a healthy individual which of the following would be low Contractility Preload Stroke volume or Afterload.?
afterload
When your stroke volume increasesdoes this improve your fitness?
Your muscles will not get as fatigued but your fitness would improve slightly i suppose.
Would stroke volume increase or decrease if your unhealthy?
Stroke volume can decrease if you are unhealthy. Health conditions such as heart failure, heart disease, or dehydration can negatively affect the heart's ability to pump blood effectively, leading to a decrease in stroke volume.
How would decreasing blood volume effect stroke volume and cardiac output?
This can be expressed simply as "less in, less out". The less blood in the system means that there will be less to be pumped out. This can be a dangerous situation where someone has lost a lot of blood. Some way to stop the loss is immediately necessary and a transfusion may be also required when it can be done.
Which jar would have the greatest volume cotton balls marbles flowers marshmallows?
marshmallow
Why would an increase in stroke volume lead to a drop in resting heart rate?
I may be guessing here but I am thinking with an increase in stroke volume you body is getting more volume per beat ... therefore it compensates by lowering the heart rate. if your pump is more efficient then you body doesn't need your heart to pump as often. That's the only rationale i can think would cause it!
