Topic 14.1: Homeostasis in mammals (CIE International A-level Biology)

This bundle contains 7 fully-resourced and detailed lessons that have been designed to cover the content of topic 14.1 of the CIE International A-level Biology specification which concerns homeostasis in mammals. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and previous knowledge checks allow them to assess their progress on the current topic as well as challenging them to make links to other related topics. Most of the tasks are differentiated to allow differing abilities to access the work and be challenged.

The following sub-topics are covered in this bundle of lessons:

• The importance of homeostasis
• The role of negative feedback mechanisms in the homeostatic control systems
• The role of the nervous and endocrine systems in homeostasis
• Deamination of amino acids and the urea cycle
• The gross structure of the kidney and the detailed structure of the nephron
• The process of ultrafiltration and selective reabsorption in the formation of urine
• The roles of the hypothalamus, posterior pituitary gland, ADH and the collecting ducts in osmoregulation
• The regulation of blood glucose concentration by the release of insulin and glucagon
• The role of cyclic AMP as a secondary messenger
• The stages of cell signalling
