Webactive transport through cell membranes. The cell membrane Some tissues have spaces between their cells through which drug molecules can pass relatively freely. The lining of blood capillaries is an example. However, most have few intercellular pores. Water-soluble molecules and ions cannot cross the lipophilic region. They have to pass through
