| Bacteria | are tiny, primitive cells that lack nuclei. They cause infection by parasitizing tissues or otherwise disrupting normal function. |
| fungi | simple organisms similar to plants but lack the chlorophyll pigments that allow plants to make their own food. Because they cannot make their own food, fungi must parasitize other tissues, including those of the human body. |
| Protozoa | are protists, one-celled organisms larger than bacteria whose DNA is organized into a nucleus. Many types of protozoa parasitize human tissues. |
| Pathogenic animals | are large, multicellular organisms such as insects and worms. Such animals can parasitize human tissues, bite or sting, or otherwise disrupt normal body function. |
| Copper | Key component of many enzymes |
| Decomposition reactions | The breakdown of a complex substance into two or more simpler substances. |
| Catabolism | Chemical reactions that break down larger food molecules into smaller chemical units and, in so doing, often release energy. |
| Anabolism | Involving the many chemical reactions that build larger and more complex chemical molecules from smaller subunits |
| Cohesion | Hydrogen bonds hold molecules of water together |
| Electrolytes | Other inorganic substances include acids, bases, and salts. These substances belong to a large group of compounds |
