Question

Which of the following would increase blood pressure?

Low heart rate
Low blood volume
Dilated blood vessels
Constricted blood vessels

Answer 1

Think about it.
1) If your heart rate is slow, that would also decrease blood pressure
2) If a person has low blood volume, the heart would have to work a bit harder to circulate the blood through the body
3) If the blood vessels expand, that would decrease blood pressure - similar to if you were to turn your garden hose on - without a nozzle, or finger to restrict the flow of water [or blood ;)]
4) Using the example from above, if a blood vessel is restricted (like a garden hose with your thumb covering part of the opening), that largely increases the pressure
