Chemicals in Smoke Project There are many chemicals

in cigarette smoke that are also found in other products. Find five examples of these products in magazines by using the “What’s in Cigarette Smoke?” worksheet as a reference. Cut the product out of the magazine to create a collage that represents a visual image of products that contain the same chemicals as cigarette smoke.

Respiratory System Definitions

Nose- The preferred entrance for outside air

into the respiratory system. Mouth

Oral cavity in which air also enters the respiratory system, especially when nasal passage may be temporarily obstructed, as by a cold or during heavy exercise.

Respiratory System Definitions

Throat Collects incoming air from the nose and mouth

and passes it downward to the windpipe.

Windpipe The passage leading from the throat to the

lungs.

Voice box Contains vocal chords and creates sound by

moving air.

Respiratory System Definitions

Alveoli Very small air sacs that are the destination of

air breathed in.

Esophagus The passage leading from the mouth and throat

to the stomach.

Ribs Bones supporting and protecting the chest

cavity and they help the lungs expand and contract.

Respiratory System Definitions

Diaphragm The strong wall of muscle that separates the

chest cavity from the abdominal cavity. By moving downward, it creates suction in the chest to draw in air and expand the lungs.

Bronchial Tubes There are one for each lung, which

subdivide into each lobe of the lungs.

Respiratory System Definitions

Bronchioles The smallest subdivisions of the

bronchial tubes at the end of which are the alveoli.

Epiglottis A flap of tissue that guards the entrance

to the windpipe, closing when anything is swallowed that should go into the esophagus and stomach.

Short-term Effects of Cigarette Smoking

Bad Breath Stale smell of tobacco

Odor of smoke on clothes, hands and hair

Deadened taste buds

Caused by constant exposure to heat, smoke and chemicals

Stuffy Nose Mucus build up

Irritated throat Mucus build up and

chemicals damage throat lining

Yellow fingers, nails and teeth Caused by tar

Long-term Effects of Cigarette Smoking

Wrinkled Skin Less oxygen in bloodstream

reaches the skin cells

Damaged Cilia Tar builds up and clogs cilia

Less Oxygen to Body

Cause headaches Decreases energy Breathing during activity is

difficult

Cuts heal slower Decreased blood circulation

Increased heartbeat Could cause heart attack

Drugs in body Nicotine gets into the brain

8 seconds after it is inhaled into the system

Sores in Mouth Caused by exposure to tar

and hot smoke in mouth

Diseases related to smoke Chronic Bronchitis

Inflamed mucus membrane in bronchial tubes

Mucus builds up/ paralyzes cilia

Bad Cough Can be cured if

cigarette smoking terminates

Emphysema Air sacs break

down/ become clogged and burst

Shortness of breath

Usually follows chronic bronchitis

Can not be cured

Diseases related to smoke Lung Cancer

Abnormal cell growth that destroys healthy cells

Tar irritates the lining of the lungs

85% of all lung cancer deaths are caused by smoking

Heart Disease Added workload

on the heart and blood vessels

Cholesterol build up

Stroke/ heart attack

Spit Tobacco Stains on teeth Tooth loss/ gum

disease Bad breath Mouth, lip, tongue,

gum cancers Leukoplakia (pre-
