Why do premedical students study physics, chemistry, and biology?

Premedical students are required to study physics, chemistry, and biology to ensure they are well-versed in the scientific method and fundamental content before entering medical school.1

These foundational subjects are essential because they allow medical programs to teach complex disciplines—such as anatomy, physiology, biochemistry, and pharmacology—with greater precision and efficiency. By mastering these core sciences, students gain the necessary background to understand the cellular and molecular mechanisms of disease, which are central to modern evidence-based medicine. Furthermore, because medicine relies on the same natural laws that govern the inanimate and animate realms, a strong grasp of physical and chemical principles is vital for analyzing physiological processes at the cellular and molecular levels.1234
