Tobacco Presentation Transcript

Slide 1 - Tobacco - Inside the Body ©Photographs courtesy of Manchester University Pathology Department This Powerpoint is hosted on www.worldofteaching.com Please visit for 1000+ free powerpoints
Slide 2 - Human female chromosome map (XX). Alcohol and nicotine addiction may be in the genes (1)
Slide 3 - 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)
Slide 4 - Clubbing of the fingers is a common condition which may indicate cancers, liver diseases and lung disease (16)
Slide 5 - Clubbed fingers - a sign of heart disease (21)
Slide 6 - Focal dust emphysema is commonest in cigarette smokers and coal miners.The black colour in this lung is due to cigarette smoke (22)
Slide 7 - Cells lining the bronchus- here there are no cilia- they have been damaged by the nicotine (23)
Slide 8 - Cells lining the bronchus the large nuclei are in cancerous cells spreading along the bronchus (24)
Slide 9 - Lung tissue blackened by smoke and showing large spaces due to emphysema (25)
Slide 10 - Emphysema- these large spaces are due to the breakdown of the air sacs in the lungs (26)
Slide 11 - Lungs: The picture on the left is of emphysema (large air sacs) and the picture on the right is of normal lung.(27)
Slide 12 - 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)
Slide 13 - Cancer of the bronchus has spread into the lungs (29)
Slide 14 - A blue colouration occurs when blood circulation is poor such as heart failure, shock and exposure to cold environments.(30)
Slide 15 - 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)
Slide 16 - Damaged toes due to poor blood circulation- will lead to amputation (32)
Slide 17 - Amputated fingers- often as a result of damage to blood vessels due to smoking (33)
Slide 18 - Franks sign - an ear lobe crease thought to be indicative of heart problems (34)
Slide 19 - Franks sign- ear lobe creasea sign of heart disease (35)
Slide 20 - Fluid collecting in the tissues, note the dent where somebody has pressed on top of the hand- a sign of heart failure (36)
Slide 21 - 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)
Slide 22 - 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. (38)
Slide 23 - Expansion of finger ends- associated with chronic breathing and heart problems (39)
Slide 24 - Expansion of finger ends- associated with chronic breathing and heart problems (40)
Slide 25 - Cancer of oesophagus- this is where the oesophagus meets the stomach (41)
Slide 26 - Cancer of the kidney- the cancer growth is the white tissue (42)
Slide 27 - 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)
Slide 28 - Bladder cancer - the bladder is a hollow bag for storing urine- here it is cut open showing a large cancerous growth inside (44)
Slide 29 - Cancer of the pancreas (45)
Slide 30 - 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)
Slide 31 - Stomach ulcers (dark brown) - alcohol and smoking are factors (49)
Slide 32 - Stomach ulcers (dark brown)- alcohol and smoking are factors. The stomach is cut open. (50)
