| A | B |
| Epithelial Tissue | Closely packed cells; found in linings and skin |
| Connective Tissue | Loosely packed cells with many blood vessels; most versatile |
| Muscle Tissue | Provides movement |
| Nerve Tissue | Responsible for relaying messages |
| Cell Specialization | Cells have specific functions and rely on other cell types |
| Tissue | Group of cells that work together for one specific function |
| Striated Muscle | Same as skeletal muscle; all voluntary movement |
| Smooth Muscle | Involuntary muscles in digestion, blood vessels, and eyes |
| Cardiac Muscle | Muscle tissue specific to the heart |
| Bone Tissue | Most rigid tissue of the body |
| Loose Connective tissue | Found beneath epithelial tissue |
| Dense Connective tissue | Resists pulling forces, such as ligaments and tendons |
