Heart and Blood Vessel Basics
Electrical Signals and Blood Flow
Electrical signals created by the S-A node follow a natural electrical pathway
through your heart walls. The movement of the electrical signals causes your
heart's chambers to contract and relax. When a signal passes through a chamber
wall, the chamber contracts. When the signal has moved out of the wall, the
chamber relaxes.
You know, mikey wants everyone to believe he's an emt. Let's hope for the sake
of his "patients" they are the brakes, as human or engine (electrical based)
operations would be in bad shape otherwise.
Remember, he's the one that said there could never have been a biblical flood
because of the partial pressure of water.
