Bulk flow and diffusion

WebBulk diffusion or convection in the bulk: transportation of the adsorbate molecules from the bulk to the adsorbents. • Molecular (or film) diffusion or external mass diffusion: transportation from the bulk solution to the adsorbent surface by diffusion through the boundary layer or liquid film surrounding the adsorbent particles ( Table 3.2 ). WebBulk flow and diffusion are two methods by which molecules move from one place to another place. Bulk flow refers to the movement of a fluid driven by a pressure gradient. Diffusion is the movement of molecules down the concentration gradient. Both processes take place during human breathing.

WebIt describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion. While the bulk flow of air from the external environment happens due to pressure changes in the lungs, the mechanisms of alveolar gas exchange are more complicated. WebLarger, more complex animals and smaller, simpler animals rely on bulk flow and diffusion to deliver oxygen to their cells. c. Only oxygen, not carbon dioxide, moves across the respiratory surface by diffusion. d. Circulation requires a pump to generate pressure to drive flow, whereas ventilation does not. e.

What is bulk flow in diffusion? - Reimagining Education

WebConvection-enhanced delivery is based on the interstitial infusion of an appropriate cytotoxic drug into the white matter at low pressure. Thus, the method employs bulk flow, distributes a drug in a larger tissue volume and eventually achieves drug concentrations greater than systemic levels. WebNov 27, 2009 · The drug is translocated in the body by bulk flow and diffusion. If the drugs chemically differ, still the transfer by bulk flow can occur by the same mechanism but if the drugs are moving by diffusion, it means that their movement is markedly different. The transfer of drug is depends on its solubility in lipid or water.
