Conversation

I learned that the heart pumps both oxygenated and unoxygenated blood.

Really? I didn't know there was a difference between the two.

Yeah, the unoxygenated blood goes to the lungs to get oxygen.

That makes sense! It’s fascinating how our bodies work.

Synonyms & Antonyms

Root Explanation

Unoxygenated → It is formed from "un-" (meaning not) and "oxygenated" (from "oxygen" which comes from the Greek "oxus" meaning sharp or acid, and "genes" meaning born of or produced by). The word "unoxygenated" means not containing oxygen or lacking oxygenation.

Memory Tip

Think of 'not' ('un-') combined with 'oxygenated', which refers to something that has oxygen. This helps you remember that 'unoxygenated' means lacking oxygen.
