Health science is one of the most practical and interdisciplinary areas of science that students study in high school. Combining biology, medicine, anatomy, physiology, nutrition, exercise science, and public health, health science helps students understand how the human body functions and how healthy choices influence lifelong wellbeing.

One of the strongest predictors of success in health science is vocabulary knowledge.


Students who understand scientific terminology are better prepared to read medical texts, interpret health information, analyze scientific research, explain biological processes, and communicate accurately using evidence-based language. Whether students pursue medicine, nursing, physiotherapy, sports science, public health, biomedical research, or another STEM career, mastering health science vocabulary provides an invaluable academic foundation.


This guide provides a comprehensive collection of health science, medicine, and physical education vocabulary words for high school students, along with practical teaching strategies and ideas for strengthening scientific literacy through reading passages, discussion, and inquiry-based learning.
