The amount of venous vessel pressure causes the 'venous return' which maintains blood volume. This is driven by the efferent pathway of the sympathetic nervous system which causes the constriction of the blood vessels which pushes the red blood cells in the veins back to the heart (flow is one way due to valves in the veins).
What else can I help you with?
How is hydrostatic pressure related to blood pressure?
gravity is not just a force, its also is a signal , a signal that tells the body how to act, on earth blood pools in the feet ,when people stand the blood pressure in there feet can be high
The force with which the contract causes blood pressure?
the force with which what the contract causes blood pressure
What can affect the force of gravity?
air pressure
Which fundamental force contributes to pressure in both water and the atmosphere?
The fundamental force that contributes to pressure in both water and the atmosphere is gravity. Gravity causes the weight of the water or air above a certain point to exert a force downwards, which leads to pressure at that point.
Is the force of the blood on the walls of the?
this is blood pressure
Blood pressure is exerted by the blood on the walls of blood vessels as a result of?
force/pressure
Force per unit area defines which of the following a) pressure b) gravity c) force d) temperature?
pressure
Is blood pressure the regular beat of blood flow?
Blood pressure is the force of your blood going through you body. Your systole number is the force of the blood coming from the heart, and the average number is 120. Your diastole is the force of the blood returning to the heart, and the average number is 80. Your systole number is higher than your diastole number because the heart has to beat greater in order to get the blood to the upper half of your body, which means it has to defy gravity. :)
What is definition of blood pressure?
Blood Pressure: Is the force at which blood flows thorugh the arteries of the body.
When The balance of forces that keep a star from collapsing is called?
The balance of forces that keep a star from collapsing is called hydrostatic equilibrium. This equilibrium is maintained between the inward force of gravity and the outward force generated by gas pressure within the star.
How much preasser is gravity?
The pressure of gravity on a surface is(total force of gravity on the surface) divided by (area of the surface)
Which animal has the highest blood pressure?
The giraffe has the highest blood pressure of any animal, reaching levels around 280/180 mmHg during times of stress. This is necessary to maintain blood flow to their brain against the force of gravity on their long neck.
