Based on AQA biology specification

Students should be able to describe the principles of hormonal
coordination and control by the human endocrine system.

The endocrine system is composed of glands which secrete chemicals
called hormones directly into the bloodstream. The blood carries the
hormone to a target organ where it produces an effect. Compared to the
nervous system the effects are slower but act for longer.

The pituitary gland in the brain is a ‘master gland’ which secretes
several hormones into the blood in response to body conditions. These
hormones in turn act on other glands to stimulate other hormones to be
released to bring about effects.

Students should be able to identify the position of the following on a
diagram of the human body:
• pituitary gland
• pancreas
• thyroid
• adrenal gland
• ovary
• testes.
