Physioex Questions Exercise 5 Question
and answers 100% correct 2025
Blood flow is measured in - correct answer ml/min.
what has the greatest effect on blow flow - correct answer blood vessel radius
the opening of the blood vessel where the blood flows is called the - correct
answer lumen
what do you think will happen to the flow rate if the radius is increased by
0.5mm? - correct answer the flow will increase
how are vessel radius and fluid flow related? - correct answer they are
directly proportional
when increasing the flow tube radius the fluid flow rate will - correct answer
increase
explain how the body establishes a pressure gradient for fluid flow - correct
answer by the heart constriction and the pressure gradient is then made.
Explain the effect that the flow tube radius change on the flow rate - correct
answer As the tube radius increases so does the flow rate.
Why do you think the plot was not linear? - correct answer Because the
radius and flow rate increase isn't proportional.
, Is plasma protein a formed element? - correct answer No
what is not a contribution to the viscosity of the blood? - correct answer
oxygen level in the blood
Viscosity most directly affects - correct answer peripheral resistance
what is the relationship between fluid flow and viscosity? - correct answer
they are inversely proportional to each other
What effect does aplastic anemia have on blood flow - correct answer
increased blood flow due to decreased viscosity
By increasing viscosity it resulted in - correct answer decrease of flow rate
what effect would a decreased hematocrit have on blood flow - correct answer
decreased viscosity, increased flow
Describe the components in the blood that affect viscosity - correct answer
white blood cells, red blood cells, platelets and plasma proteins
Explain the effect that the viscosity change has on flow rate - correct answer
when viscosity increases, the flow rate of blood decreases
describe the graph of flow versus viscosity (Exercise 5, Act.2) - correct answer
the viscosity and flow rate have inverse proportion
when the length of blood vessels increases, what also increases? - correct
answer both friction and surface areas
