carbon, hydrogen, oxygen and nitrogen make up the bulk of the atoms in the human body. However, there are many trace elements present as well. Pick three of these trace elements and do a little Internet research to find out where they're found and what they're used for in the body.

Answer #1

Calcium is found in the body, specifically in the "bones" or the "teeth".

They are converted to other materials which aid in human body skeletal structure. It is required for our muscles to move (flex/contract)

Sodium, is used in the nervous system extensively, it is used as a conector between neurons. It is actually used as a sodium ion connector.

Chlorine; is used as Hydrochloric acid, HCl, in your stomach, it aids and helps in the digestion of everything that goes into the stomach. It is the main component of "gastic juices".

Carbon Dating: All living organisms contain two isotopes (types) of carbon; carbon-12 ( 12C) and carbon-14 (14C). Carbon-12 is stable, meaning that its atoms do not decay. Carbon-14 however, is radioactive or unstable, meaning that an atom of carbon-14 may decay. It does this by throwing off an electron and thus transforming itself into Nitrogen 14. The ratio of carbon-14 to carbon-12 is the same for all living organisims, about 1/10, 000. However, once an organisim dies the carbon-14 begins...

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...
