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.

Web∙ Both bulk flow (also called mass flow) and diffusion are involved in the path of an oxygen molecule to your cells: → The oxygen molecules via ______ _____ from the air outside your body into the air space of the alveoli. This is an ________ process, but it requires the contraction of your diaphragm and rib muscles. WebApr 15, 2024 · One of the keys to efficient diffusion of any material is distance. You want a molecule to be as ___ to its destination as possible. close Bulk flow moves ___ numbers of molecules quickly. large Your ___ system is setup to take advantage of bulk flow and simple diffusion. respiratory bipartisan women\u0027s caucus
What is bulk transport biology A level? [Fact Checked!]
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.
