Transport in mammals REVISION (Topic 8 CIE International A-level Biology)

This fully-resourced REVISION lesson has been written to challenge the students on their knowledge of the content of topic 8 (Transport in mammals) of the CIE International A-level Biology specification. The engaging PowerPoint and accompanying resources will motivate the students whilst they assess their understanding of the content and identify any areas which may require further attention.

The wide range of activities have been written to cover as much of the topic as possible but the following specification points have been given particular focus:

• The significance of the oxygen dissociation curves at different concentrations of carbon dioxide (The Bohr effect)
• The role of haemoglobin in carrying oxygen
• The role of haemoglobin in carrying carbon dioxide
• Draw the structures of red blood cells, neutrophils, monocytes and lymphocytes
• The relationship between the structure and function of a capillary
• The internal structure of the heart and its associated blood vessels
• Explain how heart action is initiated and controlled
• The pressure changes of the cardiac cycle
• The relationship between the structure and function of arteries and veins
• The double, closed circulatory system of a mammal

Quiz rounds such as “Does this FLOW correctly” and “YOU DO THE MATH” are used to test the students on the finer details of their knowledge of the blood vessels and numerical facts
