Explanation:
- The question asks for the four major types of tissue in the human body.
- These are standard categories taught in basic biology/anatomy.
- Epithelial tissue covers surfaces (like skin or lining of organs).
- Connective tissue supports and connects other tissues (like bone, fat, blood).
- Muscle tissue allows movement (skeletal, smooth, cardiac).
- Nervous tissue sends and receives signals (brain, spinal cord, nerves).
- The worksheet lists them in order, and the blanks match these four names.
