    What main components in cigarettes affect the respiratory system and explain their effects on specific organs, cells and/or processes in the respiratory system?

    Explain how smoking might lead to increased levels of carbon dioxide in the blood since there are alternate mechanisms of transporting carbon dioxide.

    Can smoking affect other organ systems in the body? I need examples.

    How can you correlate cellular respiration with the respiratory system?

    Does smokeless tobacco present a reduced risk for lung cancer and other smoking associated diseases? Give evidence for answer.

    Good afternoon.

    Although there are many chemicals present in a cigarette, there are 2 that are especially hazardous to the respiratory system. These are the smoke itself and the tar. The smoke is harmful to the respiratory system because it contains CO, carbon monoxide (the same stuff that come out of the tailpipe of your vehicle).

    The CO binds with hemoglobin in the blood, thus preventing oxygen from binding. This leads to oxygen deprivation. Since oxygen is important in ATP production, this would lead to less ATP being produced by the body, which would mean there is less energy available for the body to carry on metabolism.

    Also, within components of the respiratory system, are cilia.Their job is to filter out irritants like dust, pollen, chemicals, and other harmful stuff that is in the air. The combustion of the tobacco causes the cilia to slow down their motion. When this happens the mucus moving along the respiratory ...
