Lysosomes are organelles that contain digestive enzymes. In some cases, the contents of lysosomes are released directly to the environment, a process known as exocytosis. This can occur during fertilization of animal eggs, where the contents of the lysosomes in the sperm help to break down the protective layer surrounding the egg. It can also occur during rheumatoid arthritis, where the contents of the lysosomes in the synovial cells help to break down the cartilage in the joints. Autophagy is the process by which cells break down their own components, and does not involve the release of lysosomal contents to the environment.
