|
______ in veins prevent backflow due to gravity. |
Valves |
|
|
Tick tunica media in arteries. _______ control arterial size.
|

|
The force exerted by blood on the walls of blood vessels? |
Blood Pressure |
|
|
Blood pressure is caused by ______ acting on the heart and resistance to flow as blood moves through vessels. |
Pumping |
|
|
Arterial pressure is ______ than Venous pressure due to proximity to the heart. |
Higher |
|
|
Maximum pressure exerted on walls of arteries? |
Systolic Pressure |
|
