3 Heart Sounds

D.4.U6:  Normal heart sounds are caused by the atrioventricular valves and semilunar valves closing causing changes in blood flow (Oxford Biology Course Companion page 688).

  • State the cause of each of the two sounds of the heartbeat.


D.4. NOS:  Developments in scientific research followed improvements in apparatus or instrumentation—the invention of the stethoscope led to improved knowledge of the workings of the heart (Oxford Biology Course Companion page 687).

  • List variables that lead to the development of the stethoscope.

  • State the function of the stethoscope.

4 Heart Beat

6.2.U8:  The heartbeat is initiated by a group of specialized muscle cells in the right atrium called the sinoatrial node (Oxford Biology Course Companion page 298).

  • Define myogenic contraction.

  • Outline the role of cells in the sinoatrial node.


6.2.U9:  The sinoatrial node acts as a pacemaker(Oxford Biology Course Companion page 299).

  • State the reason why the sinoatrial node is often called the pacemaker.


6.2.U10:  The sinoatrial node sends out an electrical signal that stimulates contraction as it is propagated through the walls of the atria and then the walls of the ventricles (Oxford Biology Course Companion page 299).

  • Describe the propagation of the electrical signal from the sinoatrial node through the atria and ventricles.


D.4.U2:  Signals from the sinoatrial node that cause contraction cannot pass directly from atria to ventricles (Oxford Biology Course Companion page 685).

  • Explain the events of the cardiac cycle, including atrial and ventricular systole and diastole and the movement of the signal to contract through the heart.

  • Outline the role of the atrioventricular node in the cardiac cycle.


D.4.U3:  There is a delay between the arrival and passing on of a stimulus at the atrioventricular node (Oxford Biology Course Companion page 686).

  • Outline the causes of the delayed initiation of contraction of ventricles. 


D.4.U4:  This delay allows time for atrial systole before the atrioventricular valves close (Oxford Biology Course Companion page 687).

  • State the function of a delayed contraction of the ventricle.


D.4.U5:  Conducting fibres ensure coordinated contraction of the entire ventricle wall (Oxford Biology Course Companion page 687).

  • Describe the motion of the signal to contract from the AV node through the ventricles.

  • List features of Purkinje fibers that facilitate rapid conduction of the contraction signal through the ventricle.

  • State that the contraction of the ventricle begins at the heart apex.


D.4.U1:  Structure of cardiac muscle cells allows propagation of stimuli through the heart wall.  (Oxford Biology Course Companion page 685).

  • Compare cardiac muscle tissue to skeletal muscle tissue.

  • Contrast cardiac muscle tissue to skeletal muscle tissue.

  • Describe how the Y-shape, intercalated discs and gap junctions of cardiac muscle cells allow for propagation of the stimulus to contract.

D.4.A1:  Use of artificial pacemakers to regulate the heart rate (Oxford Biology Course Companion page 689).

  • State the purpose of an artificial pacemaker device.
