摘要: Publisher Summary The chapter focuses on the hierarchies of function within individual columnar absorbing cell intestinal mucosa. It discusses possible routes whereby substrate molecules can traverse a cell, boundaries which are limited by plasma membrane and interior filled with cytoplasm (cytosol) in organelles, possessing various degrees permeability, immersed. Transcellular transport is consequence sequential operation one or more at least five different modes movement. These fundamental are: (1) extracellular transcellular movement through tubular systems piercing cell; (2) combination that flows; (3) entrainment vesicle bounded flowing membrane; (4) across membrane, either simple diffusion chemical specific channels located traversing (membrane transport); (5) transcytoplasmic .
