Question

why is the human body compared to a fine - tuned machine?

Explanation:

The human body is compared to a fine - tuned machine because it has multiple complex systems (like the circulatory, respiratory, and nervous systems) that work together in a highly coordinated manner. Each part has a specific function, and they all contribute to the overall operation and maintenance of the body, similar to how different components of a machine work together for its proper functioning.
