Blood pressure is affected by main factors.
If vascular resistance increases, blood pressure will .
Vascular peripheral resistance occurs when blood cells and plasma contact blood vessel walls.
Vasoconstriction of the muscular arteries would result in a decrease in blood pressure.
Blood , or thickness, affects peripheral resistance.
A higher than normal hematocrit will result in an increase in blood pressure.
The longer the total vessel , the greater the resistance encountered, and the greater the blood pressure.
Blood vessels are static structures so they cannot be gained or lost once adulthood is reached.
Blood volume has little to no effect on blood pressure.
Anything that affects heart rate or stroke volume affects cardiac output and blood pressure.
