The LungsBelow is the subsystem that solves the equations for the lungs.

Physiological notes:Simulation notes:
- The lungs are based on slightly different equations than most other subsystems because measurements of arterial and venous flow rates and blood pressures are easier to come by than measurements of resistance.
- The Goto and From blocks P2i and F3i are connections to other circulatory systems where the information flow is opposite of blood flow. Using the Goto and From blocks for these connections allows the connections to be made "below the surface", thereby keeping the main block diagram (physbe) uncluttered and less confusing.
- The Goto blocks, P2o, V2i, and V2o allow key output information to be passed directly to the Analysis Subsystem, where it can be managed in one central location.
- The line labels are used to keep track of variable information, making the flow of information easier to track.
