Lysosomes and Phagosomes

The Vacuolar Apparatus
  • Christian de Duve


Lysosomes were first described as cell particles or granules. I am now inclined to call them vacuoles, even when they appear as compact bodies, in order to emphasize the essentially extracellular character of their contents. Together with the phagosomes, they form what is conveniently referred to as the vacuolarapparatus [1], an intracellular digestive system comparable, except for its discontinuity, to the digestive tract of higher organisms. Each vacuole is to some extent equivalent to a certain segment of this digestive tract.
