Phase 1 — Start Here

Cell Biology Foundations

Your body is made of about 37 trillion tiny factories called cells. Each one needs oxygen, water, and fuel to do its job. When a cell factory breaks down, that is disease. When you understand how the factory works, you understand why symptoms happen, why medications help, and what to do as a nurse.
