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.
The Golgi apparatus is abundant in secretory cells, such as cells of the pancreas. Golgi Vesicle: A membrane-bound body that forms by budding from the Golgi apparatus. It contains proteins (glycoproteins), such as digestive enzymes, and migrates to the cell (plasma) membrane. Golgi vesicles fuse with the cell membrane and discharge their contents into the exterior of the cell through a process called exocytosis. Some Golgi vesicles become lysosomes which are involved in intracellular digestion.
