* pathways across the epithelium of the placenta.

Paracellular transport
* accounts for only a small fraction of total intestinal nutrient transport.
* is by passive diffusion or by solvent drag.

Passive transport
* includes diffusion and osmosis.
* is an extremely important way for small molecules to get into and out of cells
* occurs down a solute s concentration gradient.
* requires no energy from the cell.
