Why are mechanisms needed to maintain venous return? -
Answer>>The pressure of the blood in large veins is very low
which makes it difficult to get blood back to the heart

What are the mechanisms needed to maintain venous return? -
Answer>>Skeletal muscle pump, respiratory pump, pocket
valves, smooth muscle in veins, heart

What is the skeletal muscle pump? - Answer>>When muscles
contract and relax, they press on veins squeezing blood back to
the heart

What is the respiratory pump? - Answer>>When muscles
contract and relax during breathing, pressure changes occur in
the chest cavity which compress nearby veins squeezing blood
back to the heart

What are pocket valves? - Answer>>Valves in veins keep the
blood flowing in one direction and close to prevent backflow

What does the smooth muscles in veins do? -
Answer>>Squeeze the blood back to the heart

How does the heart help to maintain venous return? -
Answer>>The heart acts as a suction pump when it contracts
and relaxes

,What is the impact of blood pressure on venous return? -
Answer>>When the systolic blood pressure increases, there is
an increase in venous return and vice versa

What is the equation for blood pressure? - Answer>>Blood flow
x resistance

What is blood pressure? - Answer>>The force exerted against
the vessel wall

What is systolic pressure? - Answer>>The pressure in the
arteries when the ventricles contract

What is diastolic pressure? - Answer>>The pressure in the
arteries when the ventricles relax

Where is blood pressure measured? - Answer>>At the brachial
artery in the upper arm

What is a typical blood pressure reading at rest? -
Answer>>120/80 mmHg

blood vessel and the distance from the heart

What is the blood pressure in arterioles? - Answer>>Medium

What is the blood pressure in capillaries? - Answer>>Low

What is the blood pressure in the venules? - Answer>>Low

What is the blood pressure in the veins? - Answer>>Low

,What is the total area of arteries? - Answer>>Low

arterioles, capillaries, venules, veins, heart

What type of walls do arteries have? - Answer>>Thick elastic
walls. Have a smooth muscle layer

What is the lumen of an artery like? - Answer>>Small lumen

What pressure and velocity do arteries carry blood under? -
Answer>>High pressure and high velocity

Where do arteries carry blood? - Answer>>Away from the heart

, Does an artery contain valves? - Answer>>No

What are the walls of veins like? - Answer>>Thinner less elastic
walls with less smooth muscle than arteries

What is the lumen of veins like? - Answer>>Large lumen

What pressure and velocity do veins carry blood under? -
Answer>>Low pressure and medium velocity

Where do veins carry blood? - Answer>>Back to the heart

What do veins contain? - Answer>>Non return valves

What is the wall of a capillary like? - Answer>>One cell thick, no
outer or middle layer

What is the lumen of a capillary like? - Answer>>Microscopic
lumen

What pressure and velocity do capillaries carry blood under? -
Answer>>Very low pressure and very low velocity

What do capillaries do? - Answer>>Deliver oxygen and glucose
to tissues and remove waste products from tissues

Do capillaries contain valves? - Answer>>No

What happens after ten minutes in a warm environment? -
