By the end you’ll be able to

Explain the principle of homeostasis and negative feedback, identifying receptors, coordination centres, effectors and corrective responses in maintaining internal conditions within narrow limits.
Describe and explain the hormonal control of blood glucose concentration, including the roles of insulin, glucagon, the pancreas, the liver, glycogenesis, glycogenolysis and gluconeogenesis.

Apply knowledge of diabetes mellitus to explain the causes, symptoms, monitoring and biological basis of type 1 and type 2 diabetes and evaluate management strategies where required.

Explain thermoregulation in mammals, including the roles of the hypothalamus, skin receptors, vasodilation, vasoconstriction, shivering, sweating, piloerection and behavioural responses.

Describe the control of blood water potential and the significance of maintaining appropriate solute concentrations, linking this to osmoregulation and hormonal control.

Explain the importance of regulating blood chemistry such as carbon dioxide concentration and pH, including the role of ventilation in maintaining suitable conditions for enzyme activity and cell function.
