💧 Lymphatic Fluid Return and Lymphedema Simulator

Follow interstitial fluid as it enters lymphatic capillaries and gets propelled by one-way valves and skeletal-muscle pumping, then see how blocking a lymph node causes downstream swelling.

Medicine & Biophysics3DModerate60 FPS

The simulation traces interstitial fluid entering lymphatic capillaries and moving through one-way valves under skeletal-muscle pumping, then shows how blocking a lymph node causes fluid to back up and swelling to develop downstream.

🔬 What It Demonstrates

🎮 How to Use

Use the muscle-pump activity slider to drive fluid flow through the vessel network, then click a lymph node to block it and watch swelling accumulate in the downstream tissue region over time.

💡 Did You Know?

The human body recycles roughly two to three liters of leaked plasma fluid and protein back into the bloodstream every day, entirely through the low-pressure lymphatic network.
