Question

Which of the following would increase blood pressure? Low heart rate Low blood volume Dilated blood vessels Constricted blood vessels

Answer 1

 If your heart rate is slow, that would also decrease blood pressure If a person has low blood volume, the heart would have to work a bit harder to circulate the blood through the body  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 ;)]  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
