Illustrating two blood capillaries (Cap) inserted into the intercellular space between the columnar cells (CC). The cytoplasm of the left columnar cell (CC) is flattened by the pressure of the capillary. Microvilli (Mv) are not so well developped. Two light layers are seen: 1. between the cell membrane of the columnar cell and the
