Vessel structure explorer
Click a vessel type to compare wall layers, pressure, flow and key features.
What you’re looking at
Quick compare
Arteries: thick muscle + elastic recoil. Capillaries: exchange surface. Veins: low pressure + valves.
Drag & drop assessment
Drag each feature into the correct vessel type. Get feedback and a score.

Why the answers matter
This connects structure to function: pressure, diffusion distance, and how blood returns to the heart.
Heart + circulation simulation
Watch oxygenated (red) and deoxygenated (blue) blood move through pulmonary + systemic loops and organ capillary beds.
Controls
These controls adjust how fast particles move (a simplified proxy for flow).
About this simulation
This is an interactive teaching simulation (not a medical device). It’s designed to help learners connect structure ↔ function.
What’s included
- Cross-section explorer for artery, capillary, vein
- Drag-and-drop assessment with scoring and hints
- Animated pulmonary + systemic circulation loops with organ capillary beds
How to run
Open this folder in a local web server (recommended), or open the HTML file directly.
python3 -m http.server 5173
Then open: http://localhost:5173/
