Heart Anatomy Quiz

Nine questions on one organ

The nine questions here stay inside and immediately around the heart. They cover the chambers and the valves between them, the vessels that carry blood to and from the organ, and the structure that sets its rhythm — the pacemaker. It is naming and locating throughout: which part is which, what sits where, what a given structure is called on the diagram. Nothing in the set is clinical, and nothing on this page will name a part for you ahead of time.

The heart rewards this kind of focused set because so many of its parts come in matched pairs and layered sequences. Keeping the labels straight is exactly the work the questions ask for.

The checking behind the answers

Before this quiz existed, its answers were written twice. Two authors filled in the same fixed catalog of 200 keys — questions plus supporting tables — without seeing each other’s work. The copies were then compared value by value, and 200 out of 200 agreed. Only questions where both authors independently landed on the same answer are asked here; a value either one hesitated on never became a question at all.

What happens when you play

Every question shows four options. Select one and the result is immediate: right or wrong, with the correct answer displayed either way. Once all nine are answered, the page lays out a review of the full round so you can see exactly where the misses were. Your best score is kept in your browser.
