When you visit a clinic for a checkup, fill out medical forms about your health history, or follow medical advice from your doctor, you're engaging with the medical world.

Medical describes both the scientific knowledge behind healthcare and its practical application. Medical researchers study diseases in laboratories, discovering new treatments and cures. Medical professionals like doctors, nurses, and pharmacists apply that knowledge to help sick or injured people recover.

You might hear about medical school, where doctors train for years to master human anatomy, diseases, and treatments. A medical record contains information about someone's health over time. Even something as simple as a medical appointment demonstrates how science and care combine to keep people healthy.
