WebSam. An "electrochemical gradient" is a combination of two factors: an "electrical potential difference" between the inside and outside of the membrane and a "concentration gradient." In Khan's example, the "electrochemical graident" is established due to the sodium/potassium pump and the carrier protein's ability to allow potassium to travel ... WebJan 17, 2024 · Interstitial fluid is removed through the surrounding lymph vessels, and eventually ends up rejoining the blood. Sometimes the removal of tissue fluid does not function correctly and there is a buildup, called edema. The Starling equation describes the pressure gradients that drive the movement of water across fluid compartments.
WebThe pressure gradient is directly dependent upon blood vessel radius which essentially controls blood flow. The bigger the blood vessel radius, the more blood flow or fluid flow. … WebThis creates a pressure gradient that causes oxygen to dissociate from hemoglobin, diffuse out of the blood, cross the interstitial space, and enter the tissue. Hemoglobin that has little oxygen bound to it loses much of its brightness, so that blood returning to the heart is more burgundy in color. Figure 3.
Jan 5, 2024 · WebIn the case of atmospheres, the pressure-gradient force is balanced by the gravitational force, maintaining hydrostatic equilibrium. In Earth's atmosphere, for example, air pressuredecreases at altitudes above Earth's surface, thus providing a pressure-gradient force which counteracts the force of gravity on the atmosphere.
