| Crohn's Disease can affect any part of the alimentary canal, from the mouth to the anus, but commonly affects the small and large intestines. |
| The larvae, or nymphs, have feathery gills – located in the anus – that are especially vulnerable to toxins. |
| At the same time you are locking the opening to the anus, pull that string. |
| This is accomplished by first locking the opening to your anus by squeezing the muscles of your buttocks together. |
| Breathing through the anus allows nymphs to propel themselves through the water with a sudden, turbo-charged burst of speed to escape predators. |
| By holding a thermometer for at least one minute in the anus of an animal, its temperature can be measured. |
