Cardiac Cycle Anatomy And Physiology Ii Relate heart sounds detected by auscultation to action of heart’s valves. the period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle. the period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. it starts at the beginning of one heartbeat and ends at the beginning of another. the process begins as early as the 4th gestational week when the heart first begins contracting.
Cardiac Regulation вђ Human Physiology Phases of the cardiac cycle. at the beginning of the cardiac cycle, both the atria and ventricles are relaxed (diastole). blood is flowing into the right atrium from the superior and inferior venae cavae and the coronary sinus. blood flows into the left atrium from the four pulmonary veins. the two atrioventricular valves, the tricuspid and. The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( figure 19.3.1 ). the period of contraction that the heart undergoes while it pumps blood into circulation is called systole. the period of relaxation that occurs as the chambers fill with blood is called diastole. The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( figure 19.27 ). the period of contraction that the heart undergoes while it pumps blood into circulation is called systole. the period of relaxation that occurs as the chambers fill with blood is called diastole. Describe the effect of medullary cardiac centers on the activity of the heart. describe each of the four phases of the cardiac cycle. in your discussion describe what is happening to ventricular volume and pressure, whether the atria are in systole or diastole, whether the ventricles are in systole or diastole, whether the atrioventricular valves are open or closed, whether the semilunar.

The cardiac cycle is a series of pressure changes that take place within the heart. these pressure changes result in the movement of blood through different chambers of the heart and the body as a whole. these pressure changes originate as conductive electrochemical changes within the myocardium that result in the concentric contraction of cardiac muscle. valves within the heart direct blood. Learning objectives. after studying this chapter, you will be able to: identify and describe the interior and exterior parts of the human heart. describe the path of blood through the cardiac circuits. describe the size, shape, and location of the heart. compare cardiac muscle to skeletal and smooth muscle. explain the cardiac conduction system.
