To apologize (verb) is to issue an apology (noun).
Excuse oneself is knowing and accepting the reasons of a mistake. Apologize is presenting one's excuses for a mistake.
To apologize is a verb meaning to retract an insult or other injury and offer regrets that it happened. Sorry is an adjective meaning, among other things, feeling regretful. Thus when you make an apology you can say "I apologize" (apologize is the verb) or "I am sorry" (am is the verb).
The difference between one apologising and one being sorry is very subtle. If one were to 'apologise', one would be admitting that something they did was wrong, but not necessarily caring. If one were to be 'sorry', they are not only admitting that they were wrong but owning up to it and actually feeling remorse.

These two words can be confusing. Here's a good rule of thumb: Use "that" whenever the identity "that" is replacing is known to the speaker. Examples: I will read the book that is written by my favorite author. (not: "which is written..") All that I can see from here is beautiful. She didn't even apologize, and that is why I am angry. (not: "apologize, which is why...") Use "which" whenever the speaker does not know what "which" is. Examples: Which route will we take to get there? I do not know which [one] is the better car.
