Tar is a nasty collection of a variety of substances inhaled during smoking. This is often where the carcinogens accumulate, so the tar is associated with oral, throat and lung cancer. There are also many chemical irritants, so tar is also associated with Asthma, COPD, ephysema and infections of the respiratory tract.
Carbon Monoxide
Carbon Monoxide will always be detected in the blood, but after 1-2 days the level will be no different to that of a non-smoker.
Yes, it is possible for carbon monoxide from cigarette smoke to reach someone on oxygen therapy if they are in close proximity to the smoker. However, the oxygen therapy should still be providing a higher concentration of oxygen to the person, which can help mitigate the effects of the carbon monoxide exposure. It is important to avoid exposure to cigarette smoke when using oxygen therapy to prevent any adverse health effects.
When you breathe in a lung-full of cigarette smoke, the carbon monoxide passes immediately into your blood, binding to the oxygen receptor sites and figuratively kicking the oxygen molecules out of your red blood cells. Hemoglobin that is bound to carbon monoxide is converted into carboxyhemoglobin, and is no longer able to transport oxygen. This means that less oxygen reaches a smoker's brain and other vital organs. Because of this added carbon monoxide load, a smoker's red cells are also less effective in removing carbon dioxide-a waste product-from his or her body's cells.
Carbon monoxide could have entered Don's bloodstream through exposure to car exhaust fumes while stuck in traffic on his way to work. Sitting in a car with poor ventilation can lead to the accumulation of carbon monoxide, which can be absorbed through breathing.
When you smoke, gases such as carbon monoxide, ammonia, hydrogen cyanide, and formaldehyde are produced. These gases are harmful to both the smoker and those exposed to secondhand smoke.
The reticulocyte increases in person with the smoking history.
Carbon monoxide binds tightly to the hemoglobin in red blood cells, instead of the oxygen that they should normally carry. So when you breathe in, the CO molecule attaches to the blood cell rather than the O2 molecule, and your cells don't get enough oxygen. CO can kill.
smoker this is your website not mine
hi.. .it is the carbon monoxide that binds to the Hb (haemoglobin),to form carboxyhaemoglobin. the nicotine tar gets accumulated in the alveoli of the lungs eventually leading to a condition called smoker's lungs. patients will present with early morning cough, rusty sputum and other symptoms of respiratory disease
Second hand smoke... it is nasty >:(
The cigar smoke contains tar, which is made up of more than 4,000 chemicals, including over 60 known to cause cancer. Some of these substances cause heart and lung diseases. Some are known for their adverse effects on bones and skins. Once inhaled, smoke condenses and about 70 per cent of the tar in the smoke is deposited in the smoker's lungs.
