Coordination and response — IGCSE Sciences - Co-Ordinated (0654) questions by topic
Locating nervous-system structures on a skin cross-section, naming the control mechanism that keeps blood glucose within limits, linking a fight-or-flight pulse-rate rise to adrenaline release, and identifying labelled parts on a skin diagram underpin the 12 coordination and response questions from 2023 and 2024, worth 7 to 12 marks.
State and identify are the leading command words, with complete, calculate and describe used where a mechanism or trend must be explained rather than a single structure named. Because these diagram-labelling questions reward exact anatomical vocabulary, work through them here and submit for instant marking, so a mislabelled receptor or gland is flagged immediately rather than costing marks on a related follow-up.
