1

Flow equals

Change in pressure over resistance

2

Mean arterial pressure

CO x TPR

3

In a parallel circuit total resistance will

always be less than the resistance of the smallest circuit

4

What would happen to total peripheral resistance in a in a parallel circuit if another circuit was added

It would decrease regardless of the magnitude of the newly added circuit

5

What would be the effect of hematocrit on viscosity>

High hematocrit, in a situation like polycythemia would lead to high blood viscosity. Low hematocrit on anemia leads to low blood viscosity

6

Determinants of resistance in laminar flow?

resistance = (8 x fluid viscosity x tube length)/ pi x radius to the fourth

7

Murmurs more likely with low or high hematocrit

high
