Example:
Imagine trying to figure out why your smartphone won’t turn on. Just like each part of a smartphone has a specific role—like the battery providing power or the screen displaying information—a biological organ has a 'function,' which refers to its special, normal, or proper activity within the body. In both cases, understanding the role or function of each component is crucial: the battery’s failure to charge might be the problem with the smartphone, much like how a malfunctioning heart might disrupt blood circulation in the body.
