The Cardiac Cycle - The Lub Dub of a Heartbeat

Learn about the cardiac cycle!
Why does the heart make the famous heartbeat sound? Ever wondered what happens during a heartbeat?
This video discusses the two phases of the cardiac cycle (diastole and systole), the heart movements during a heartbeat (ventricle contraction and relaxation, valves opening and closing), the blood flow during a heartbeat, and what those two numbers in blood pressure measurements represent.
