What is sensitive to changes in pressure or to movement of fluid?
Mechanoreceptors
The primary means of water movement between fluid compartments is?
The movement of water and electrolytes is primarily regulated between fluid compartments by hydrostatic pressure and osmotic pressure.
What happens as the concentration gradient of the intersititial fluid increases?
As the concentration gradient of the interstitial fluid increased, the potassium concentration increased and there was a noticeable decrease in urine volume excreted.
The pressure a fluid in a closed container exerts can be increased by thrust?
Yes it can because of the movement...
Why the divergent part of venturimeter is longer than convergent part?
Actually when the flow emerges from the throat area of venturi to enter into the diverging section, their is a negative pressure gradient i.e, in layman terms fluid is trying to flow from low pressure region to high pressure region according to Bernoulli equation. In this adverse pressure gradient, there is boundary layer separation, in simple terms, the fluid leaves the surface of the wall. Due to this there can be energy loss or the fluid can't recover the pressure fully leading to head loss. So if divergent section is long that means more gradual diverging section, due to which the adverse pressure gradient is less so less chance of boundary separation and hence less loss. Also large diverging section will ensure proper development of flow, i.e. fluid sticking to the wall back after separation.
What is fluid gradient?
Usually a fluid gradient refers to the pressure gradient in any kind of fluid. It is a quantity that shows which direction and how fast the pressure changes around a location.
What is the gradient called that is the driving force for the movement of water and dissolved solutes from the arterial ends of blood capillaries?
The blood pressure in the capillaries at arterial end is about 25 to 30 mm of Mercury. The oncotic pressure of the plasma proteins is about 22 mm of mercury. So there is net force, which drives out the fluid in the interstitial space. The fluid is sucked back at the venous end of the capillaries by the oncotic pressure of the plasma proteins. It should be called as pressure gradient.
What is the driving force for fluid flow?
pressure gradient is
What conditions must be present for a fluid to flow?
pressure gradient
What establishes the lymph pressure gradient?
The fluid pressure gradient in the lymphatic system is established by two things. The first is movements caused by breathing, and the second is contractions of the skeletal muscles.
What is the difference between low pressure gradient and high pressure gradient system?
A low pressure gradient is a state where the difference in the fluid density between one side of a divider is close to the fluid density of the other side. A high pressure gradient is a state where the difference in the fluid density between one side of the divider is very different to the fluid denisity of the other. For instance, a cell wall is permiable and allows some matter to migrate across the barrier through diffusion. If your blood fluid is carrying a small amount of salt compared to a high salt content on the interior of the cell, there is a high pressure gradient between the two fluid medium. The cell will swell and diffusion will try to balance the salt content from one side of the cell wall to the other by migrating fresh water into the cell and migrating salt to the outside.
The movement of fluid through the cell membrane from a high pressure area to a lower pressure area is called?
active transport

How does the body establish a pressure gradient for fluid flow?
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).
What is the Capillary fluid shift mechanism?
exchange of fluid that occurs across the capillary membrane between the blood and the interstitial fluid. This fluid movement is controlled by the capillary blood pressure, the interstitial fluid pressure and the colloid osmotic pressure of the plasma. Low blood pressure results in fluid moving from the interstitial space into the circulation helping to restore blood volume and blood pressure.
