How to Pronounce Coronary Sinus

Say it like this: KOR-oh-ner-ee SY-nus. The first word rhymes with "worry" but starts with a K sound, and the second word rhymes with "sinus" like the space in your nose. The stress falls on the first syllable of each word: KOR and SY.

The stress is on the first syllable of each word: KOR-oh-ner-ee and SY-nus. A common mistake is putting the stress on the second syllable (ko-RON-ary), but the correct way emphasizes the beginning of each word.

The term has five syllables total: cor-o-nar-y si-nus. "Coronary" has four syllables, and "sinus" has two syllables.

"Coronary" comes from the Latin word "corona," which means "crown." It's used in anatomy because the blood vessels around the heart form a crown-like pattern on the organ's surface.

In medical language, "sinus" means a channel, cavity, or hollow space—not just the air spaces in your face. In this case, it refers to a vein-like channel on the heart.

The coronary sinus is basically a collecting tube on the back of the heart that gathers used blood from the heart muscle and sends it back to the main chamber. Think of it like a drain that collects water from different parts of a sink.

Yes! You might hear "coronary artery" or "coronary heart disease." All of these terms refer to structures or conditions related to the crown-like blood vessels around the heart.

Yes, doctors and nurses sometimes abbreviate it as "CS" in written notes, but you'll usually hear the full term "coronary sinus" spoken aloud in conversation.

Here's an example: "The doctor pointed to the coronary sinus on the heart diagram to show where the cardiac veins drain." This sentence shows the term being used to describe a part of the heart's structure.
