structures

In biology, structures refer to the specific parts or components of an organism, like organs, tissues, or molecules, that work together to perform vital functions. For example, the heart’s structure includes chambers and valves that enable it to pump blood efficiently. Structures are organized in a way that supports the organism's survival and health. Think of them as the "building blocks" or "blueprints" designed to ensure proper function, stability, and coordination within the body or a cell. Understanding structures helps us grasp how living things are built and how they operate smoothly.
