a: blood flow ~
b: a ladder of progress
What:
"Don't think of blood flow like a single loop from arteries to veins. Think of it like a ladder where it flows up one side, across the rungs, then down the other side. If you cut off the top few feet of the ladder, you still have the rest of the rungs."
