| kidneys | organs in the body that work to eliminate excess Nitrogen from the body |
| lungs | organs in the body that work to eliminate excess Carbon Dioxide from the body |
| Nitrogen | element found in the air that is necessary for making proteins |
| nutrition | the science that deals with food molecules and nutrients |
| organic | any molecule containing Carbon |
| Oxygen | element found in the air that is necessary in breathing and metabolism |
| photosynthesis | process that plants use to get Carbon from the air and into food for us |
| protein | food molecule composed of amino acids; contains 4 Calories per gram |
| saturated | type of fat that has only single bonds; contains as much Hydrogen as possible |
| unsaturated | type of fat that has some double bonds and is harder to digest |
| vegetables | one of the categories of MyPlate; includes green beans, peas, avocado, peppers |
