Discover the amazing systems inside your body. Tap organs on the interactive silhouette to see what they do, explore how your heart, lungs, and brain work together, and test your anatomy knowledge with fun quiz games.
Tap any glowing pinpoint on the silhouette to inspect it.
Pumps oxygen-rich blood through arteries and veins to every cell in your body.
Your heart beats about 100,000 times every day without ever taking a rest!
Your body systems never work alone! The lungs bring in oxygen, the heart pumps it through the blood, and the brain coordinates every movement.
Vital organs, body systems, 5 senses, and biology learning tips.
Your body is made of billions of cells working together in organized systems: the circulatory system moves blood, the respiratory system takes in air, the digestive system processes food, and the nervous system sends signals.
The brain is the control center. The heart pumps blood continuously. The lungs take in oxygen. The stomach and intestines extract energy from food, while the kidneys and liver filter waste.
The skeleton of 206 bones gives your body structure and shields fragile organs. Muscles contract and pull on bones so you can move, jump, and smile.
Your eyes (sight), ears (hearing), nose (smell), tongue (taste), and skin (touch) gather sensory information from the world and send electrical signals to your brain.
Place your hand on their chest to feel their heartbeat, and take a deep breath to observe their chest expanding.
Understanding organs helps you appreciate the importance of clean water, balanced nutrition, sleep, and physical activity.

It is a free interactive anatomy tool for beginners to discover internal organs, body systems, and the 5 senses through an interactive silhouette and quizzes.
The major vital organs include the brain, heart, lungs, liver, kidneys, stomach, and intestines.
The heart pumps oxygen-rich blood through arteries to the entire body, and veins return oxygen-depleted blood back to the lungs.
An adult human skeleton has 206 bones that provide strength, structure, and protection.
The five traditional senses are sight (eyes), hearing (ears), smell (nose), taste (tongue), and touch (skin).
Practice mode offers three self-paced quizzes: matching organ jobs, identifying body systems, and answering sensory clues.
