Review your knowledge of basic heart structure using the KScience drag and drop. There is a mistake in the terminology used see if you can spot it.

Measuring blood pressure is helpful animation from Sumans Inc. that explains it further.


 * Assessment statements** (IBO notes added to some point to clearly indicate what needs to be understood and what does not)
 * H.5.1 || Explain the events of the cardiac cycle, including atrial and ventricular systole and diastole, and heart sounds. ||
 * H.5.2 || Analyse data showing pressure and volume changes in the left atrium, left ventricle and the aorta, during the cardiac cycle. ||
 * H.5.3 || Outline the mechanisms that control the heartbeat, including the roles of the SA (sinoatrial) node, AV (atrioventricular) node and conducting fibres in the ventricular walls. Bundles of His and Purkinje fibres are not required. ||
 * H.5.4 || Outline atherosclerosis and the causes of coronary thrombosis. ||
 * H.5.5 || Discuss factors that affect the incidence of coronary heart disease. ||

Steven Taylor ( [|i-Biology] ) has a great presentation to view and take notes from before starting your notebook media type="custom" key="24444946"
 * Presentations and tutorials **

The Hyper Heart is a great resource from Pharmacology Animations for understanding the cardiac cycle (H.5.1 and H.5.2). Tutorials on all the phases which match the animation are provided. N.B. It gives more detail than the three named phases you are asked to understand. media type="custom" key="20537768" animation source: @http://library.med.utah.edu/kw/pharm/hyper_heart1.html

[|MedMovie's cardiovascular library]contains lots of useful tutorials and printable summaries. Particularly useful are atherosclerosis and common heart problems.

 * Approach**

[|Biointeractive's cardiology lab] is an interesting activity, but goes beyond this topic and what students need to understand.
 * Interesting Extras **

In 1924 Einthoven was awarded the Nobel prize in Physiology or Medicine for his discovery of the mechanism of the electrocardiogram. Apart from acknowledging his discovery this link has a small section on how the heart beat works.

Learn how to read an ECG by reading this well written accessible article from the South Sudan Medical Journal.
