This fully-resourced lesson explains the relationship between the structure and function of arteries, veins and capillaries. The engaging and detailed PowerPoint and accompanying resources have been designed to cover point 8.1 © of the CIE International A-level Biology specification.
This lesson has been written to build on any prior knowledge from GCSE to enable students to fully understand why a particular type of blood vessel has particular features. Students will be able to make the connection between the narrow lumen and elastic tissue in the walls of arteries and the need to maintain the high pressure of the blood. A quick version of the GUESS WHO game is used to introduce smooth muscle and collagen in the tunica media and externa and again the reason for their presence is explored and explained. Moving forwards, the lesson considers the structure of the veins and students are challenged to explain how the differences to those observed in arteries is due to the lower blood pressure found in these vessels. The final part of the lesson looks at the role of the capillaries in exchange. Links are made to diffusion to ensure that students can explain how the red blood cells pressing against the endothelium results in a short diffusion distance.
It is estimated that it will take about 2 hours of allocated A-level Biology teaching time to cover the detail included in this lesson

Topics 7 & 8: Transport in plants & mammals (CIE A-level Biology)
This bundle contains 11 fully-resourced lessons which will engage and motivate the students whilst covering the following specification points in topics 7 and 8 of the CIE A-level Biology specification: TOPIC 7 * The structure of xylem vessel elements, phloem sieve tube elements and companion cells * The relationship between the structure and function of xylem vessel elements, phloem sieve tube elements and companion cells * Explain how hydrogen bonding of water molecules is involved with the movement in the xylem by cohesion-tension in transpiration pull and adhesion to cell walls * The pathways and mechanisms by which water and mineral ions are transported from the soil to the xylem and from roots to leaves * Assimilates move between sources and sinks between phloem sieve tubes * The mechanism by which sucrose is loaded into the phloem * The mass flow of phloem sap down a hydrostatic pressure gradient TOPIC 8 * The double, closed circulatory system of a mammal * The relationship between the structure and function of arteries, veins and capillaries * The role of haemoglobin in carrying oxygen and carbon dioxide * The significance of the oxygen dissociation curve of adult haemoglobin at different carbon dioxide concentrations * The external and internal structure of the heart * The cardiac cycle * The role of the SAN, AVN and Purkyne tissue in the initiation and conduction of the heart action The lesson PowerPoints and accompanying resources contain a wide range of tasks which include exam-style questions with mark schemes, discussion points and quiz competitions that will check on current understanding as well as making links to previously covered topics.

Topic 8: Transport in mammals (CIE International A-level Biology)
Each of the 7 lessons in this bundle are fully-resourced and have been designed to cover the content as detailed in topic 8 (Transport in mammals) of the CIE International A-Level Biology specification. The specification points that are covered within these lessons include: * The double, closed circulatory system of a mammal * The relationship between the structure and function of arteries, veins and capillaries * The role of haemoglobin in carrying oxygen and carbon dioxide * The significance of the oxygen dissociation curve at different carbon dioxide concentrations (Bohr effect) * The external and internal structure of the mammalian heart * The cardiac cycle, including the blood pressure changes during systole and diastole * The initiation and control of heart action The lessons have been written to include a wide range of activities and numerous understanding and prior knowledge checks so students can assess their progress against the current topic as well as be challenged to make links to other topics within this topic and earlier topics If you would like to see the quality of the lessons, download the arteries, veins and capillaries lesson as this is free
