Transcript of Elements in the human body and Earth's crust

Elements What are elements? Elements in the Human
body and in Earth's crust By: Lexi Cortes :) Pure substances
Composed of atoms
Fundamental materials The Human Body Most abundant element: Oxygen 96% of the mass of the human body is made up of these elements... Purposes 1. Helps us live 2. Body's transportation system 3. Lubricant 4. Regulates body Temperature 1. Stable bonds with
hydrogen and oxygen 2. fuels growth and
movement. 1. Goes with oxygen 1. Make up protiens 2. DNA http://www.deltacollege.edu/emp/ckim/Chem3A/Kane/Chapter04.pdf Other elements
in the body... The Earth's Crust There are over 100 elements known. 88 are found
in nature. 97% of the earth's mass is
made up of these eight elements. Oxygen
Magnesium Oxygen
Nitrogen 21% Volume
89% Mass Not found free in nature
Silicon Dioxide Oxygen Silicon Aluminum Metal
Processing bauxite Connections or
Similarities? Our bodies are made mostly out of water as is the earth. To make water you need hydrogen and oxygen which are key factors for our survival and Earths. Our bodies are made up of roughly 6% of minerals..some of which are found in Earth's crust. Iron is found in rocks and is a key essential for good health in humans. Biggest surprises IRON... Second most abundant metal in earth's crust
but what about anemia? 1 mg is lost per day. Calcium... 5th most abundant In the human body and in the earth's crust, the vast majority of calcium is present in the sequestered form Works Cited Zumdahl, Steven S.
