carbon monoxide & tar
TRANSCRIPT
Carbon monoxide is an odorless, colorless gas that is highly toxic in nature.
While cars emit carbon monoxide, so do cigarettes and other smoke-able tobacco products as the tobacco itself is burned.
The gas is formed when plant materials burn. It can combine with haemoglobin in blood, reducing the blood’s capacity to carry oxygen.
Carbon monoxide in tobacco smoke is thought to be associated with the increased risk of heart disease from smoking.
CARBON MONOXIDE
The most harmful of the gases in cigarette smoke is carbon monoxide which is the same gas as that in car exhaust.
Carbon monoxide (CO) replaces oxygen in the blood, making it difficult for the body's cells to get all the oxygen they need.
CO also promotes cholesterol deposits in the arteries,
contributing to cardiovascular disease.
Elevated CO blood levels impair vision and judgment, making smoking potentially dangerous to drivers.
EFFECT OF CO
Over time, as more and more carbon monoxide binds to hemoglobin, a smoker's arteries harden, which can cause the following health complications:
blood clotsgangrene, which can lead to the need for amputationheart attackheart diseasepulmonary embolism, a condition in which a blood clot
trapped in the lungs blocks the flow of oxygen to the bodystrokevascular (vein-related) disease.
Tar is a sticky substance found in tobacco leaves when smocked it coats the lungs and alveoli. This prevents oxygen from reaching the blood.
These gummy particles consist of a large number of toxic chemicals created by burning tobacco.
Although cigarette filters are intended to trap tar and spare smokers from excess tar exposure but toxins still make it through and can leave a brown-yellow film behind
Tar impacts human health in a number of ways, including increasing the risk of bronchitis, emphysema and lung cancer.
TAR
The tar in cigarettes can stain smokers' teeth and turn them yellow or brown.
Cigarette tar can stain anything it touches brown, including a smoker's hands and clothing.
The tar in tobacco cigarettes is a major cause of lung cancer, emphysema and bronchitis. The toxins from the tar can damage lung cells that keep tumors from forming.
Cigarette tar also damages cilia in the lungs, which protect the lining of the lungs.
EFFECTS OF TAR
Inflammation of the lining of the airways connecting the trachea to the lungs, called the bronchial tubes, occurs when the tissues become irritated.
It becomes harder than normal to breathe, resulting in a
consistent, hacking cough.
Chronic bronchitis causes bronchial tubes to be red and swollen on a continuous basis and produce excessive mucus over time.
Decreased immune system reactions may make killing off bacterial infections difficult.
BRONCHITIS
Emphysema develops when the air sacs at the base of tiny air passages called bronchioles gradually break down smoking.
The irritating chemicals in cigarette smoke, including tar, are the leading cause of emphysema.
Symptoms include shortness of breath, chest tightness, chronic coughing, fatigue and decreased physical activity ability.
Emphysema eventually prevents oxygen entering the lungs from reaching the blood stream.
EMPHYSEMA
An increased risk of lung cancer correlates to the estimated total milligrams of tar from cigarette smoke to which a person is exposed.
Lung cancer ranks as the leading cause of cancer deaths for Americans.
Preventing or stopping the use of tobacco, including exposure to tar, could nearly eliminate lung cancer.
If caught in an early stage, the five year relative survival rate for lung cancer is 31 percent.
LUNG CANCER
Smoking affects the respiratory system because it stops the small little hairs called Cilia in your throat. They are used to push dirt and mucus out of your throat.
The tar also sticks to the lining of your throat and lungs (this makes fingers yellow).
It contains a lot of carbon monoxide which sticks to the
hemoglobin in the blood instead of oxygen.
Mucus which would also be removed through cilia goes in to blood stream and is deposited in arteries.
