Conversation

Have you ever heard of the term postcaval?

I think I read about it in a biology book once.

Yeah, it's related to the postcaval vein, right?

Exactly! It's interesting how our bodies have so many complex parts.

Root Explanation

Postcaval → It is formed from "post-" (meaning after) and "caval" (from Latin "cavus", meaning hollow). The term "postcaval" refers to structures or veins located behind the hollow or cavity, particularly in anatomical contexts.

Memory Tip

Think of something that is located 'after' ('post-') a 'hollow' space ('cavus') — that's why postcaval refers to something behind a hollow structure.
