Coordination and control: hormones and the human endocrine system

Why this why now
Prior knowledge requirements
- Humans are multicellular organisms – they are made up of millions of living cells.
- Specialised cells in animals have shapes, sizes and structures that are adapted for the jobs the cells do.
- The circulatory system transports substances around the body in the blood.
- The human body has a nervous system that enables us to sense and respond quickly to changes outside and inside the body.
- Receptors detect stimuli.
- Sensory neurons transmit nerve impulses from receptors to processing centres such as the brain in the CNS.
- Motor neurons transmit nerve impulses from the CNS to effectors that carry out responses.

Coordination and control: hormones and the human endocrine system
This unit explores hormonal control by the endocrine system, including blood sugar regulation by insulin and glucagon, and the roles of thyroxine and adrenaline. It covers the importance of maintaining a stable internal environment and compares types 1 and 2 diabetes and their treatments.
