Circulation Diagrams, Instantly

What does a circulation diagram explain?

A circulation diagram traces blood through the pulmonary circuit between heart and lungs and the systemic circuit between heart and body tissues. A schematic prioritizes connections and direction over realistic anatomy.

Use it to learn the route

Choose this diagram when learning vessel names, comparing the two circuits, or explaining oxygenation changes. A detailed heart anatomy illustration serves a different purpose from a simplified flow overview.

Make the flow easy to follow

1. Draw arrow directions. Every connection should show where blood travels next.
2. Name vessels by direction. Arteries carry blood away from the heart and veins return it; oxygen content alone does not define them.
3. Separate the circuits. Make it clear which path passes through the lungs and which serves body tissues.
4. Explain the colors. Use a legend for oxygenation status rather than suggesting blood is literally blue.
5. Keep detail appropriate. Add chambers and valves only when they help meet the lesson’s learning objective.

Build from the level of detail you need

MyMap places the structures you request on a canvas and connects them with arrows. The example is a simplified lungs-heart-body schematic with major vessels; it does not depict the individual heart chambers. Ask for those separately when needed.
