The burning part. All combustion requires oxygen.
Oxygen is consumed and polluted by burning of cigarettes.
Deforestation reduces the gross amount of oxygen produced by an ecosystem it reduces the amount of oxygen produced .
Cigarettes are harmful to the development of a fetus, because they create a degree of carbon monoxide poisoning in the mother, which reduces available oxygen to both mother and fetus, and because nicotine is also a vaso-constrictor, making blood vessels contract, thereby reducing blood flow to the fetus.
carbon, oxygen, hydrogen for sure
Deforestation reduces the gross amount of oxygen produced by an ecosystem it reduces the amount of oxygen produced .
The smoke will go through the tube and who ever has the oxygen will be breathing smoke. Also, the oxygen is highly flammable.
Cigarettes cause lung cancer, and I believe that they also can clog up the little hole in your lungs (I forget what they are called, but that is how the oxygen get to your body.
Because you use oxygen going to the brain.
Carbon monoxide reduces the oxygen saturation of hemoglobin at any given PaO2.
carbon monoxide.
Carbon monoxide is the chemical in cigarette smoke that reduces the ability of blood to carry oxygen. It binds to hemoglobin in red blood cells more readily than oxygen, displacing oxygen and impairing its transportation to tissues.
There are many dangerous substances in cigarette smoke, but I will just discuss the most dangerous three of them. Nicotine is a dangerous drug because it is strongly addictive, and it also causes blood vessels to contract (technically it is a vasoconstrictor) which reduces blood circulation. Tar, also known as polycyclic aromatic hydrocarbons, is a powerful carcinogen; it causes cancer. Carbon monoxide reduces the oxygen carrying capacity of the blood (it bonds to hemoglobin and prevents it from carrying oxygen molecules).
