How to Pronounce Renal Vein

Say it like this: REE-nul vayn. The first part rhymes with "free," and the second part sounds like the word "vain." Put the stress on the first syllable—REE—so it sounds like you're emphasizing the beginning of the word.

Renal comes from the Latin word for kidney. So whenever you see the word "renal" in medicine, it's referring to something related to the kidneys. Examples include renal artery, renal disease, and renal function.

Break it into three syllables: REE-nul vayn. The first two syllables make up "renal," and "vein" is one syllable by itself.

Many people stress the second syllable and say ruh-NAL vein, but that's incorrect. Remember to stress the first syllable: REE-nul vein. Think of it like the word "free" at the start, and you'll get it right.

A renal vein is a blood vessel that carries blood away from the kidney. It's one of two veins (you have two kidneys, so two renal veins), and they carry filtered blood back toward the heart.

A vein carries blood back toward the heart, while an artery carries blood away from the heart. Since the renal vein carries blood from the kidney back to the heart, it's called a vein, not a vein.

You'll see "renal" in words like renal artery (the vessel bringing blood to the kidney), renal cortex (the outer part of the kidney), and prenatal (which actually uses a different prefix, but shows how Latin roots appear in medical terms). All renal words are about kidneys.

You might hear: "The renal vein drains blood from the kidney." Or: "There are two renal veins in the human body, one for each kidney." These sentences just describe what the structure is and where you find it.
