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).

How do you prove equality of pressure in a continuous body of fluid?
To prove equality of pressure in a continuous body of fluid, you can apply Pascal's principle, which states that the pressure exerted at any point in a confined fluid is transmitted equally in all directions. This means that in a continuous body of fluid at rest, the pressure at any given depth is the same in all directions. You can also use the hydrostatic equation to show how pressure varies with depth in a fluid column.
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 is interstitial fluid pressure?
Interstitial fluid pressure is the pressure of the fluid that surrounds the cells in tissues within the body. It helps regulate the movement of substances between cells and capillaries. Changes in interstitial fluid pressure can affect processes such as fluid balance and transport of nutrients and waste products.
How does pressure work in the context of fluid dynamics?
In fluid dynamics, pressure is the force exerted by a fluid on its surroundings. It is caused by the molecules of the fluid colliding with each other and with the walls of the container. Pressure increases with depth in a fluid due to the weight of the fluid above pushing down. This pressure difference creates flow in fluids, such as in the movement of water through pipes or in the circulation of blood in the body.
What determines the amount and direction of fluid that flows between body compartment?
Fluid flow between body compartments is determined by a combination of factors such as hydrostatic pressure, osmotic pressure, and permeability of the membrane separating the compartments. These factors influence the movement of water and solutes to maintain fluid balance and osmolarity in different parts of the body.
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.
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 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.

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 type of osmotic pressure does the loop of henle create?
The loop of Henle creates an osmotic pressure gradient in the kidney medulla by allowing the reabsorption of water from the filtrate. This gradient is essential for the kidney to concentrate urine and maintain water balance in the body.
What is the primary function of countercurrent multiplier?
The primary function of countercurrent multiplier in the kidney is to establish and maintain the concentration gradient in the renal medulla that allows for the reabsorption of water and salts, ultimately producing concentrated urine. This process helps conserve water and maintain body fluid balance.
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.
