Some examples are the mouth, nose, eyes, lungs, stomach, and the trachea.
If an example is what you need i'll try my best to help. Say for example, you're sitting in class and you're doing a group project and you want your best friend to do it with you but (s)he thought you had meant that you wanted to do it with someone else, because of poor body or facial language.
Does this help at all?...
D is the answer hope it helps
Stay calm, figure out the pros and cons to the conflict, then talk about it.
