Intersection of Vascular and Cardiac curves

Question 1

When cardiac and vascular function curves intersect, what does the intersection point represent?

Answer 1

The point of intersection will always be the operating volume for cardiac output and venous return

Question 2

When is the only time CO may not equal VR?

Answer 2

During small transient disparities

Question 3

Does cardiac output determine venous return or does venous return determine CO?

Answer 3

Neither CO and VR are interdependent but one is not determined by the other

Question 4

What three factors determine the total flow of blood around the entire closed circuit?

Answer 4

Capability of the pump (cardiac function)
Characterisitics of the circuit (vascular function)
The volume of the blood in the circuit
