Drug

Real World Example

Imagine trying to fix a squeaky door hinge that disrupts the peace in your home. Just as applying oil to the hinge can quiet the noise and restore smooth movement, a drug interacts with the body to modify its functions and address specific issues. The oil is like the drug, the hinge represents a part of the body, and just as the oil alters the hinge's function to eliminate the squeak, the drug alters bodily functions to achieve a desired effect.
