MICROANATOMY

Detailed explanation-1: -Bulk Flow is a process that moves a large number of molecules quickly. True. During diffusion, the oxygen molecules must get through SIX layers of membrane to get to the blood cells.

Detailed explanation-2: -In living systems, diffusion is responsible for the movement of a large number of substances, such as gases and small uncharged molecules, into and out of cells.

Detailed explanation-3: -This phenomenon is also referred to as the mass flow hypothesis. It is the process of water movement via xylem tissue from the soil to the leaves and other parts of the plant. Mass flow term can also be used in reference to the flow of bulky materials like sucrose through the phloem.

Detailed explanation-4: -Bulk flow is a process used by small lipid-insoluble proteins to cross the capillary wall. Capillary structure plays a large role in the rate of bulk flow, with continuous capillaries limiting flow and discontinuous capillaries facilitating the greatest amount of flow.

Detailed explanation-5: -Filtration is the bulk movement of water across a porous membrane, and any solute that is small enough to pass through membrane pores will flow with it. Overall, filtration is governed by hydrostatic and osmotic pressures along with the pores that allow small molecules to pass through them.
