Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through. Second, the filtered fluid passes through the tubule wherein the filtered wastes are removed; minerals are sent back to the body, and the remaining output becomes urine.

<span>For the purposes of this discussion, it is important to note that elements are the basic components of Chemistry. Elements contain atoms. All substances are made up of elements. Compounds are elements that contain more than one type of atom that bond together via a chemical reaction. Mixtures are made up of more than one substance, element or compound that are not chemically bonded together. Compounds and mixtures impact our daily lives because everything we have is made up of elements. An example of a mixture is strawberry ice cream. Milk, cream, and other elements are mixed together to make the ice cream. An example of a compound is water. A droplet of water is made from two hydrogen molecules (elements) and one oxygen molecule.
