About This Quiz

If there's one thing we all know about our bodies, it's that they need healthy organs for us to exist comfortably. Organs are collections of tissues, nerves and blood vessels, each with their own role to perform in the functioning of our biology. When multiple organs work in a similar way, they then form organ systems. But before we go too far, we want to know how much you know about the body's organs.

We all know that the heart pumps blood, but do you know why it does that? The brain is the control center, but do you know just how many things it's in charge of? The stomach receives our food, but do you know what it does with it? We know the kidneys are our filtration system, but do you know what else they do?

If you didn't pay attention in biology class or weren't a pre-med major in college, you'll have to have quite the knowledge of the body to ace this quiz. If you're up to the challenge, who are we to stop you? Go ahead and prove to us that you know all about the human body and its organs in this quiz.
