This fully-resourced lesson looks at the structures that make up the gross anatomy of the heart and also covers the calculation of cardiac ouput. The engaging and detailed PowerPoint and accompanying resources have been designed to cover the 4th part of point 3.4.1 of the AQA A-level Biology specification which states that students should be able to describe the gross structure of the human heart and be able to use the equation stroke volume x heart rate to calculate cardiac output.
As this topic was covered at GCSE, the lesson has been planned to build on this prior knowledge whilst adding the key details which will enable students to provide A-level standard answers. The primary focus is the identification of the different structures of the heart but it also challenges their ability to recognise the important relationship to function. For example, time is taken to ensure that students can explain why the atrial walls are thinner than the ventricular walls and why the right ventricle has a thinner wall than the left ventricle. Opportunities are taken throughout the lesson to link this topic to the others found in topic 3.4.1 such as blood circulation and the cardiac cycle. Moving forwards, the students are introduced to the stroke volume and meet normative values for this and for resting heart rate. This will lead into the calculation for cardiac output and a series of questions are used to test their ability to apply this equation as well as percentage change.

Topic 3: Organisms exchange substances with their environment (AQA A-level Biology)
This lesson bundle contains 17 detailed and fully-resourced lessons which cover the following specification points in topic 3 of the AQA A-level Biology specification: Topic 3.1 * The relationship between the size of an organism or structure and its surface area to volume ratio * The development of systems in larger organisms as adaptations that facilitate exchange as this ratio reduces Topic 3.2 * Adaptations of gas exchange surfaces as shown by gas exchange in single-celled organisms, insects, bony fish and the leaves of dicotyledonous plants * The gross structure of the human gas exchange system * The essential features of the alveolar epithelium as a surface over which gas exchange takes place * The mechanism of breathing to include the role of the diaphragm and the intercostal muscles Topic 3.3 * During digestion, large molecules are hydrolysed to smaller molecules * Digestion in mammals by amylases, disaccharidases, lipase, endopeptidases, exopeptidases and dipeptidases * Mechanisms for the absorption of the products of digestion by cells lining the ileum of mammals Topic 3.4.1 * The structure and role of haemoglobin in the loading, transport and unloading of oxygen * The effects of carbon dioxide concentration on the dissociation of oxyhaemoglobin * The general pattern of blood circulation in a mammal * The gross structure of the human heart * Pressure and volume changes and valve movements during the cardiac cycle * The structure of the arteries, arterioles and veins * The formation of tissue fluid and its return to the circulatory system Topic 3.4.2 * Xylem as the tissue that transports water * The cohesion-tension theory of water transport * Phloem as the tissue that transports organic substances in plants * The mass flow hypothesis for the mechanism of translocation in plants If you would like to sample the quality of the lessons included in this bundle, then download the following lessons which have been uploaded for free Alveolar epithelium Absorption in the ileum Arteries, arterioles and veins Formation of tissue fluid Translocation

A huge bundle of resources! 3 x worksheets and a really detailed PowerPoint...made for a really interactive and thought provoking lesson. Key information dotted throughout the lesson to allow students to find their way through the heart and label on key features. Really clear diagram of he heart included. Good exam style questions and understanding checkpoints dotted throughout. I can't explain how finding these PowerPoints have improved my A-Level lessons. Absolute lifesaver. Not to mention saving me at least 2 hours of my day which I would have used to create something that wouldn't have been as good, Thank you GJHeducation!
