Write a paragraph as if you are a molecule of carbon dioxide in the blood that will be excreted through the lungs. Start in the
blood vessels of the lungs and finish as the breath is exhaled from the body. Be sure to include what structures are involved, what other substances are involved, the path taken out of the body, and the effect on the body.
Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom contently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.
