| Anabolism | Using the building blocks from food to construct body tissues and store carbohydrate energy; this process requires energy |
| Catabolism | The opposite of anabolism; a process in which a complex substance is broken down into its smaller components |
| Metabolism | The sum of the chemical reactions of anabolism and catabolism |
| Water | Makes up more than half of the human body; is a component of blood and fills up the space inside and between the cells; required for survival |
| Carbohydrates | Found in starches and sugars; the body's main source of energy; all carbohydrates are eventually broken down into or converted to glucose |
| Lipids | Known for their capability to store energy; also provide protection and communication between cells |
| Protein | The basic building block of the body; makes up muscles and other tissues and is found in every part of cells |
| Minerals and Trace Elements | Chemical compounds present in very small amounts in food; serve a variety of purposes in daily metabolism |
| Vitamins | Organic compounds that function as coenzymes, assisting enzymes in catalyzing chemical reactions |

| Frontal or Coronal Plane | Divides the body vertically into anterior and posterior portions |
| Sagittal Plane | Divides the body vertically into right and left parts |
| Midsagittal Plane | Goes through the exact median of the body, dividing it into two near-mirror images |
| Transverse or Cross-sectional Plane | Divides the body horizontally, into superior (upper) and inferior (lower) parts |
| Waxes | Lipids that prevent water loss within the body and protect cells |
| Steroids | Lipids that assist with the communication process between cells; composed of cholesterol, testosterone, and estrogen |
