Intercalated Cells. This type cell is found in the late distal tubule and is represented by the IC box. Its main function is acid-base balance. The basolateral border of this cell is freely permeable to hydrogen and potassium.
Intercalated discs are part of the sarcolemma and contain two structures important in cardiac muscle contraction: gap junctions and desmosomes. A gap junction forms channels between adjacent cardiac muscle fibers that allow the depolarizing current produced by cations to flow from one cardiac muscle cell to the next.
