6. See a doctor if the boil has not drained within two weeks, or has become infected. In some cases, medical treatment will be required to deal with the boil, due to its size, location, or infection. A doctor will need to lance the boil, either in his/her office or in surgery.
How do cells dispose of unwanted organic material? Although food has been broken down into individual molecules by the time it reaches a cell, cells still need to deal with larger complexes of organic material. Intracellular digestion is carried out by organelles called lysosomes. There are several contexts in which cells need to carry out digestion.
Lysosomes (common in animal cells but rare in plant cells) contain hydrolytic enzymes necessary for intracellular digestion. In white blood cells that eat bacteria, lysosome contents are carefully released into the vacuole around the bacteria and serve to kill and digest those bacteria. Uncontrolled release of lysosome contents into the cytoplasm is also a component of necrotic cell death. Katrina Â· 5 years ago.
