Oxygen (O) Human beings obtain this element from the air. It enters a person’s bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells‚ oxygen combines with chemicals obtained from food. Energy produced during this process makes it possible for each cell to perform its function in the body. Also‚ oxygen atoms are present in water and water is essential to all life. It is present in many organic compounds. While oxygen is necessary for life‚ oxygen as ozone
