Explain

In AQA GCSE Biology, Explain means give a linked reason, mechanism, or cause-and-effect account rather than naming a fact. For Animal tissues, organs and organ systems, use Explain to support the objective to explain that the heart pumps blood around the body in a double circulatory system. Related approved keywords for this objective include heart. This definition is deliberately scoped to The heart and blood vessels, so it preserves this concept without merging it with neighbouring key terms.
