Tissue samples have been taken from your lower digestive organs.

Various organs are required for digesting food. The upper digestive organs are the mouth, oesophagus, stomach and the first segment of the intestines. The liver, along with the gallbladder and the pancreas, also form part of the upper digestive organs. The lower digestive organs are the rest of the intestine and the anus.

Tissue samples have been taken from you during the course of an examination. This examination was done using a tube. A camera is attached to the end of the tube. This camera then sends images to a screen during the examination. It can then be seen whether the tissue is healthy or changed. Small tools, for example forceps, can be used during the examination. The tools are pushed forwards through the tube. Tissue samples can be taken in this way. These tissue samples can then be examined more closely under the microscope.
