Chapter 8 - Cardiovascular System

Think critically!

The quiz was generated using artificial intelligence which is known to sometimes get even basic arithmetic wrong.
In the case of Anatomy, it sometimes incorrectly counts the number of ribs in the human body, fails to select correct anatomical terms, mixes up sex hormones, etc.
Occasionally the answer it provides in the marking key isn't even a question option – this is why you might see quiz validation errors.
When in doubt, and if you're not 100% sure, refer back to a peer reviewed source like an Anatomy textbook.
