Unidirectional transport of a material from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the ecf is called unidirectional transport of a material from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the ecf is called transcellular transport secretion paracellular transport absorption

The right answer is: transcellular transport.

Water and solutes can be transported:
- through an epithelium by successively crossing the apical and basolateral membranes: transcellular transport (for example in intestinal absorption of renal filtration or reabsorption)
- between the cells through the tight junctions: paracellular transport.

In transcellular transport, one step is active and the other is passive. For example, in the case of sodium reabsorption, the active step is the basolateral sodium exit by the Na + / K + -ATPase, which consumes energy and makes it possible to maintain an electrochemical gradient favourable to the passive input of sodium across the apical membrane in the direction of the electrochemical gradient.

Swating at a bee and it stings

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
