There is accumulation of carbon (smoke) within the walls of these air sacs in the lungs. This makes the air sacs inelastic and it is difficult for air to get out of the lungs (Emphysema) (9)
The air sacs in the centre of the lung tissue in the picture have broken down. The black dots are smoke particles lodged in the tissues- this condition is emphysema. (28)
This man is a heavy smoker (see nicotine stained fingers) and has led to vascular disease which has resulted in a blood clot on one of his fingers on his right hand (31)
Heart: somebody has pressed on top of the hand- a sign of heart failure (36)This slice is also through both ventricles (compare it to photo 38) The left ventricle is towards the right of the image as you look at it, and shows a white area of in the heart wall. This is tissue, which has died due to lack of blood supply (37)
Heart: somebody has pressed on top of the hand- a sign of heart failure (36)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. (38)
Cross-section of a coronary artery (artery to the heart). The inner wall is very thick (pale pink) and you can see a massive blood clot (red) taking up much of the photo (46)
