5 True/False questions
respiratory bronchiole → branches of the terminal bronchioles that subdivide into several alveolar ducts
carbon dioxide → (CO) Sources include incomplete combustion of fossil fuels. Effects: binds to hemoglobin reducing bloods ability to carry O2. Reduction accomplished by catalytic converters, oxygenated fuel, mass transit (reduction).
emphysema → an abnormal condition of the lungs marked by decreased respiratory function
oxides of nitrogen → S + O₂ → SO₂
2SO₂+ O₂ → 2SO₃
SO₃+ H₂O → H₂SO₄, natural source: volcanoes, decay of organic matter. man made source: combustion of sulfur containing coal and smelting of sulfide ores. methods of reduction: alkaline scrubbing.
volatile organic compounds → Organic chemicals that evaporate readily and exist as gases in the air
