Document Summary
1st layer is an epithelial layer made of epithelial cells that stick together tightly to seal off lumen. 2nd layer is connective tissue which contains proteins, collagen, glycoproteins. Fibroblasts = do not form this tight layer like the epithelial cells. 3rd layer smooth muscle cells that are oriented in different orientations. Elements of intracellular cytoskeleton: actin filaments, cell-cell junctions i. Cell to extracellular matrix: microtubules, do not have a role in anchoring junctions. This protein takes up sodium in the digested food and sodium wants to diffuse into the cell. This energy is used to bring glucose into the cell. Energy of sodium gradient brings glucose into the cell. 2nd transport of glucose is passively transport because it is moving along its concentration gradient. Tight junctions have epithelial cells bound tightly to each other and do not allow for the green symporter to pass through.
