Topic 9.9: Osmoregulation and temperature regulation (Edexcel A-level Biology B)

This detailed bundle contains 6 lesson PowerPoints and accompanying resources that cover the following specification points found within topic 9.9 of the Edexcel A-level Biology B specification:

• The gross and microscopic structure of the mammalian kidney
• The formation of urea in the liver from excess amino acids
• The removal of urea from the bloodstream by ultrafiltration
• The selective reabsorption of solutes in the proximal tubule
• The differences between endotherms and ectotherms
• The regulation of temperature by endotherms by a range of behavioural and physiological responses

The wide range of tasks, which include exam-style questions with detailed markschemes, focused discussion points and quiz competitions which introduce key terms and values, will engage and motivate the students whilst the content is covered in the detail required at A-level
