How does the body establish a pressure gradient for fluid flow?
Wiki User
∙ 12y ago
A pressure gradient exists in the arteries because the heart actively pumps the blood; additionally, the elasticity of the larger arteries helps force the blood along. There is a lower pressure gradient within the veins that is generated by the muscles squeezing the blood along back to the heart (assisted by valves within the veins).

Which of the following statements about fluid pressure is correct SEE Discuss for choices?
"If you are 15 ft. under water, the pressure will be the same no matter how large the body of water is" is a true statements about fluid pressure.
What direction does pressure act in liquid?
if you are asking in which direction does a liquid exert pressure on the object? then, liquid exert force in the upward direction which is called buoyancy. Brief description: when a body is partially or wholly immersed, it displaces the fluid. the displaced fluid had tendency to regain it's original position position. due to this, an upward force is exerted on the body by the displaced fluid. this upward force actiong on the the body immersed in a fluid is called upward thrust or buoyancy force or simply buoyancy.
Does weight affect Edema?
Being overweight slows body fluid circulation and puts extra pressure on the veins
Does a pump develop flow or pressure?
the pump develops pressure to have the ability to make a flow of a gas or fluid take place through a vessel, pipework or valve system, as long as there is an open end to the pipe system or vessel allowing distribution of fluid to an outlet or a return pipe back to the pump body.
How does the human body resist the atmospheric pressure?
because our body pressure is equal to the atmospheric pressure.
What is shear flow?
Shear flow is the flow induced by a force gradient (for a fluid). For solids, it is the gradient of shear stress forces throughout the body.
Why do people have salty tears?
Water is moved from the body to the tears by creating an osmotic gradient to pull the water from the interstitial fluid. In that sense a tear (lacrimal) or sweat gland is like a small kidney in reverse. Blood pressure + osmotic pressure = tears or sweat.
How does pressure play a part in buoyancy?
The pressure equalizes between a "bouyed" body, and the "bouying" fluid, such that the pressure of the fluid, integrated over the wetted surface, equals the weight of the body.
Why is gradient important?
it is so import because the partial pressure gradients its the one the support our breating in the body
What is chest cuirass?
It is a negative pressure shell that fits the upper body. It is used to provide negative pressure to patients which provides a pressure gradient to move air into and out of the lungs.
What is the major cause of fluid pressure on the internal organs?
The ultimate source of fluid pressure in the body is the heart, whose pumping generates blood pressure.
How is the movement of oxygen in the body similar to movement of carbon dioxide?
They both follow a simple diffusion gradient : from high pressure to low.

Is osmosis driven by hydrostatic fluid typically blood pressure in body?
No filtration
Can high blood pressure result in increased interstitial fluid?
Perhaps it may induce edema, but in general, interstitial fluid is the basic body fluid.
Where is the transmission fluid pressure switch on 98 Chevy Tahoe?
On a 98 Chevy Tahoe, the transmission fluid pressure switch is located on the valve body. It is found to the right of the engine.
