Tracing Blood Through Double Circulation, Worked

State

This procedure traces one path of blood through the double-circulation loop, drawing together this chapter's heart, vessel, and pattern atoms.

Watch for

Assuming blood passes through the heart only once per full circuit, as in single circulation, is the error here — double circulation repressurizes blood at the heart twice, once between each leg of the journey.
