## How Biology Helps Us Stay Healthy
Biology is the foundation of modern medicine. By understanding how living things work, scientists and doctors can discover treatments and cures for diseases.
### Key Contributions
- Vaccines and antibiotics fight infections.
- Genetic testing helps diagnose illnesses and prevent diseases.
- Organ transplants are possible because we understand how organs function.
## Everyday Health
Biology also teaches us about nutrition, exercise, and how to prevent illness.
Examples
- Using vaccines to prevent diseases like measles and flu.
- Doctors using genetic tests to find out if someone has a risk for certain illnesses.
