At its simplest, your body is a high-performance machine. To understand how it works, you have to look at the relationship between (the structure/parts) and Physiology (the function/how those parts move and react). 1. The Hierarchical Build The brain and nerves use electrical impulses for

The primary "function" of almost every structure in your body is to maintain . This is the body’s ability to keep its internal environment stable even when the world outside changes. Structure: Your sweat glands and skin blood vessels.

The body isn't just a bag of organs; it’s built like a complex skyscraper, starting from the ground up: To understand how it works, you have to
