Did you know that the diaphragm is really important for breathing?

Yeah, I learned that in biology class! It's amazing how it works.

Exactly! It separates the chest from the abdomen and helps us take in air.

I find it fascinating how such a small muscle plays such a big role.

Root Explanation

Diaphragm → It is formed from "dia-" (meaning through or across) and "phragm" (from Greek "phragmos", meaning fence or partition). The word refers to a partition that separates different areas, particularly in the context of the muscle that separates the thoracic cavity from the abdominal cavity.

Memory Tip

Think of a 'fence' or 'partition' ('phragm') that goes 'across' ('dia-') the body, which helps you remember that a diaphragm is a muscle that separates different areas.
