Plz help!! I can't figure this out and have school today!!! Thanks everyone
Exercise 5, Activity 5:
1.)Try to explain why this graph differs from the radius plot in the vessel resistance experiment. Remember that the flow rate into the pump did not change, whereas the flow rate out of the pump varied according to your radius manipulations?
2.) As the right flow tube radius is increased, fluid flow rate (increases/decreases). This is analogous to (dilation/constriction) of blood vessels in the body.
3.) Even though the pump pressure remains constant, the pump rate (increases/decreases) as the radius of the right flow tube increased. This happens because the resistance to fluid flow is (increased/decreased).
4.) The heart must contract (more/less) forcefully to maintain cardiac output if the resistance to blood flow in the vessels exiting the heart is increased.
5.) Increasing the resistance of (that is, constricting) the blood vessels entering the heart would (increase/decrease) the time needed to fill the heart chambers.
6.) What do you think would happen to flow rate and the pump rate if the left flow tube radius is changed (either increased or decreased)?
Activity 6:
1.)What happened to the pump's rate as its stroke volume was increased? Help!!
2.) Using your stimulation results as a basis for your answer, explain why an athlete's resting heart rate might be lower than that of an average person?? Help!
3.) Applying the stimulation outcomes to the human heart, predict the effect of increasing the stroke volume on cardiac output (at any given rate)?? Help!!
