  • The Cardiac Cycle: The Cardiac Cycle

    The Cardiac Cycle The cardiac cycle is the sequence of events that occur in the heart during one heart beat. It is how the heart operates, and what exactly happens when it contracts and relaxes. The heart is equipped with four chambers and one-way valves that work with precision to pump blood to and from the body. The heart regulates blood volume to support efficient circulation to the cells, tissues, organs, and systems. It provides oxygen and nutrients to the bodies tissue while also removing metabolic waste from cells to disposal sites. It is ultimately responsible for many homeostatic actives that keep us alive and well. It beats roughly seventy-five beats per minute, which is less than one beat per second.
