"let parent = removeMe.parentNode;" What does removeMe.parentNode actually mean in this context

I am struggling to understand what the parent node actually does. I have watched the video where the instructor shows the tree.

In this context am I calling the parent element <ul>?

app.js 
const removeMe = document.querySelector('.remove_me');
let parent = removeMe.parentNode;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>Parent Traversal</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <ul>
            <li>Hello</li>
            <li>Hi</li>
            <li class="remove_me">Good bye!</li>
            <li>Howdy</li>
        </ul>
        <script src="app.js"></script>
    </body>
</html>

removeMe is simply a reference to the variable that stores the element being selected in the DOM with .querySelector. ParentNode is the method used to Traverse the Dom.. which is of course the way we move from one element to another in the DOM Tree.
