The best answer is :
Systolic circulation

The systolic blood circulation is the process when the heart contracts., the oxygen-rich blood from the heart is pumped out into the arteries, from where it is sent to all the body parts.
The node which initiates the contraction through a nerve signal is called the AV node.
