Human Body Systems Quiz

Your body is made up of 11 major organ systems, and each one has a specific job to keep you alive and functioning. If you enjoy learning how things work together, you might also like the Numbers and World Records Quiz - it tests some equally surprising facts about the world around us.

• The circulatory system and how the heart pumps blood through your body
• The digestive system and how food gets broken down into energy
• The skeletal system and how bones protect your organs - similar to how structure matters in the Rocks and Minerals Visual Quiz
• The nervous system and how your brain sends signals to control movement and thought
• How these systems work together to keep everything running

Understanding your body systems helps you make sense of why doctors ask the questions they do and why certain habits affect your health. Much like knowing the timeline behind great stories in the Famous Novels and Their Publication Years quiz, knowing your body gives you a deeper appreciation for how complex things come together.
