Human female chromosome map (XX). Alcohol
and nicotine addiction may be in the genes (1)
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)
Clubbing of the fingers is a common condition
which may indicate cancers, liver diseases and
lung disease (16)
Clubbed fingers - a sign of heart disease (21)
Focal dust emphysema is commonest in
cigarette smokers and coal miners.The black
colour in this lung is due to cigarette smoke (22)
Cells lining the bronchus- here there are no ciliathey have been damaged by the nicotine (23)
Cells lining the bronchus the large nuclei are in
cancerous cells spreading along the bronchus
(24)
Lung tissue blackened by smoke and showing
large spaces due to emphysema (25)
Emphysema- these large spaces are due to the
breakdown of the air sacs in the lungs (26)
Lungs: The picture on the left is of emphysema
(large air sacs) and the picture on the right is of
normal lung.(27)
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)
Cancer of the bronchus has spread into the lungs
(29)
A blue colouration occurs when blood circulation
is poor such as heart failure, shock and exposure
to cold environments.(30)
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)
Damaged toes due to poor blood circulation- will
lead to amputation (32)
Amputated fingers- often as a result of damage
to blood vessels due to smoking (33)
Franks sign - an ear lobe crease thought to be
indicative of heart problems (34)
Franks sign- ear lobe crease
a sign of heart disease (35)
Fluid collecting in the tissues, note the dent
where somebody has pressed on top of the
hand- a sign of heart failure (36)
Heart: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: 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 (39)
Expansion of finger ends- associated with
chronic breathing and heart problems (40)
Cancer of oesophagus- this is where the
oesophagus meets the stomach (41)
Cancer of the kidney- the cancer growth is the
white tissue (42)
Cervical cancer - the nucleus of this pink cell
should be round- instead it is mis-shapen and is
an early sign of cancer of the cervix (43)
Bladder cancer - the bladder is a hollow bag for
storing urine- here it is cut open showing a large
cancerous growth inside (44)
Cancer of the pancreas (45)
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)
Stomach ulcers (dark brown) - alcohol and
smoking are factors (49)
Stomach ulcers (dark brown)- alcohol and
smoking are factors. The stomach is cut open.
