The black dots are smoke particles lodged in the tissues- this condition is emphysema.

This is tissue, which has died due to lack of blood supply Heart: The left ventricle is towards the left of the screen, and shows enormous thickening of the wall, particularly in relation to the small cavity. The heart is almost twice the size it should be, as it has had to work much harder than normal. Expansion of finger ends- associated with chronic breathing and heart problems, again problems associated with smoking Expansion of finger ends- associated with chronic breathing and heart problems Cancer of oesophagus- this is where the oesophagus meets the stomach Cancer of the kidney- the cancer growth is the white tissue Bladder cancer - the bladder is a hollow bag for storing urine- here it is cut open showing a large cancerous growth inside Cancer of the pancreas Stomach ulcers (dark brown) - alcohol and smoking are factors Stomach ulcers (dark brown)- alcohol and smoking are factors.
