Would the given condition increase or decrease blood flow with all other factors

Question

Would the given condition increase or decrease blood flow with all other factors being equal?
Increase in blood velocity increasing vessel length increasing vessel radius vasoconstriction increasing red blood cell count Dehydration Aldosterone hypersecretion Increasing blood viscosity Would the given condition increase or decrease blood flow with all other factors being equal?
Increase in blood velocity increasing vessel length increasing vessel radius vasoconstriction increasing red blood cell count Dehydration Aldosterone hypersecretion Increasing blood viscosity
Increase in blood velocity increasing vessel length increasing vessel radius vasoconstriction increasing red blood cell count Dehydration Aldosterone hypersecretion Increasing blood viscosity

Explanation / Answer

Increase in blood velocity: increase in blood flow.

increasing vessel length: decreases blood flow

increasing vessel radius: increased blood flow.

vasoconstriction: means construction of blood vessels by narrowing blood vessels. Decreased blood flow.

increasing red blood cell count: would imply that there would be an increase in viscosity. An increase in viscosity could decrease the blood flow.

Dehydration: dehydration occurs when there is a decrease in the liquid component of blood plasma resulting in an increased RBC concentration and increased viscosity. An increase in viscosity could decrease the blood flow.

Aldosterone hypersecretion: increased blood flow.

Increasing blood viscosity: increased resistance to flow
