Bulk flow occurs due to a pressure gradient, while diffusion occurs due to a concentration gradient. Thus, this is the key difference between bulk flow and diffusion. Moreover, bulk flow moves the entire solution while in diffusion, solutes move from higher concentration to lower concentration. Further, … See more Bulk flow is the movement of a mass of fluids down the pressure gradient. Bulk flow is an important process in plants. Water and solutes … See more Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration. It occurs along the concentration gradient. Hence, it is a passive process which occurs without the use of energy. It … See more Bulk flow is the movement of substances in bulk or in masses down a pressure gradient.

WebBulk flow of air dominates in the upper airways and is the method most obvious to the observer. Gas transport takes place by means of molecular diffusion in the fine structure of the lung. The architecture of the lungs appears to be adapted to facilitate gas transport … Web• (Bulk) Flow Through Porous Media 1. It is the bulk movement of a fluid in a porous media due to hydraulic forces (pressure, matric attractive forces, and gravity). 2. It is described by Darcy's law (Eqn. 10.1) which states that the volumetric flux of a fluid is proportional to the gradient of the hydraulic potential. The

WebDiffusion occurs when molecules move from an area of high concentration to an area of low concentration. Diffusion does not require energy because the molecules move down their concentration gradient (from areas of high to low concentration). WebWhat is bulk flow diffusion respiration? The bulk flow in respiration is mainly defined as the movement of gases (oxygen and carbon dioxide) from an area of high pressure to an area of low pressure. This mechanism in breathing is mainly responsible for the changes in the shape and volume of the chest cavity, which is controlled by the ...
