SV = EDV - ESV
Therefore, stroke volume is greatest when venous return is increased.
By 1st year paramedic science student.
When venous return is increased
Increased heart rate and increased stroke volume
The crank angle would change the stroke. The stroke would change the volume.
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
It's decreased ... unless the rate falls, which is the normal cardiac response.
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
afterload
it would be the same for all
That depends on the situation you are thinking about. For example, a gravitational force is greatest when the objects are closest together.
Your muscles will not get as fatigued but your fitness would improve slightly i suppose.
which tubes?
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.
