Systemic Vascular Resistance

Question 1

the resistance that is offered to blood flow thought a vessel

Answer 1

Systemic vascular resistance

Question 2

Vasoconstriction

Answer 2

decreases vessel size, increases resistance, & increases blood pressure.

Question 3

Vasodilation

Answer 3

increases vessel diameter, decreases resistance, & decreases blood pressure.

Question 4

Which vessels are able to constrict & dilate?

Answer 4

arteries

Question 5

the higher the diastolic blood pressure,

Answer 5

the greater the resistance to blood being ejected from the left ventricle. Meaning, the left ventricle has to work harder to pump the blood out against a higher diastolic pressure.

Question 6

If the left ventricle has to contract against the high resistance chronically, it eventually weakens & fails. This is know as:

Answer 6

left ventricular failure or CHF

Question 7

causes vasoconstriction which decreases vessel diameter & increases systemic vascular resistance

Answer 7

Sympathetic stimulation

Question 8

the difference between the systolic & diastolic blood pressure readings

Answer 8

Pulse pressure

Question 9

A narrowing pulse pressure is defined as being less than ___% of the systolic blood pressure reading

Answer 9

25%

Question 10

the flow of blood through the smallest blood vessels; arterioles, capillaries & venules.

Answer 10

Microcirculation
