Explanation:

Each term is matched to its standard biological definition or associated structure:

1. An organ is a group of specialized tissues working together for a task.
2. An organ system consists of multiple organs with a shared function.
3. The cell is the fundamental unit of all living things.
4. Tissue is a collection of identical, specialized cells.
5. Muscle tissue enables body movement.
6. Nerve tissue transmits electrical signals for bodily responses.
7. Connective tissue provides structural support to organs.
8. Epithelial tissue forms protective coverings for the body and organs.
9. The skeletal system corresponds to the body's bone structure (image P).
10. The digestive system corresponds to the organs that process food (image N).
11. The integumentary system includes skin, hair, and nails.
12. The excretory system removes liquid waste from the body.
13. The circulatory system transports blood and nutrients.
14. The immune system corresponds to the body's defense network (image O).
15. The reproductive system is involved in producing offspring.
16. The endocrine system releases hormones to regulate bodily functions.
