What Are Chemicals? | How Drugs Work in the Body | Understanding Homeostasis

We’re all made of chemicals—but what exactly is a chemical? In this video, we break down the basics: chemicals are forms of matter that exist as solids, liquids, or gases. Inside living organisms, these chemicals create complex networks that keep us alive and balanced—a process known as homeostasis.

Drugs are chemicals too! They work by interacting with these biological networks to help restore or adjust how the body functions. Whether you’re a curious learner, a patient, or a future scientist, understanding these fundamentals can empower better decisions about your health and treatment.
