The organ that never stops is your metabolism. Your metabolism is the chemical processes that occur within your body to maintain life. It's responsible for converting food into energy, repairing cells, and eliminating waste products. Even when you're resting, your metabolism is constantly working to keep your body functioning.
Here are some examples of basic bodily functions that rely on your metabolism:
- Breathing: Your lungs constantly exchange oxygen and carbon dioxide, which is fueled by your metabolism.
- Circulating blood: Your heart pumps blood throughout your body, delivering nutrients and oxygen, a process driven by your metabolism.
- Maintaining body temperature: Your metabolism generates heat to maintain your body temperature, even in cold environments.
While many people believe that the nose and ears never stop growing, this is not entirely true. They do grow slightly throughout life, but the growth rate slows down significantly after puberty.
