Well if you're referring to the human body, our cells make up a lot of everything we're made of. Muscles, organs, bones, blood, skin, etc. Biologically speaking, there's a lot to the human body besides organs. Sorry if this isn't very helpful.
Organs or organ systems are directly below the hierarchical organization of life. For an organism to act or function properly organ systems are needed to exist. The following are examples of organ systems that are needed by an organism:
1. Nervous System
2. Digestive System
3. Reproductive System
4. Respiratory System
5. Muscular System
6. Skeletal System
7. Endocrine System
8. Immune System
9. Excretory System
10. Circulatory System
11. Integumentary System
