Transport in animals — IGCSE Sciences - Co-Ordinated (0973) questions by topic
Transport in animals questions cover the function of vein valves, what red blood cells transport, labelling a mammal's double circulatory system, and reading a heart-rate-against-time graph during exercise, worth from 1 to 12 marks in this IGCSE Co-ordinated Sciences set.
State, identify and describe lead the command words, with write and calculate also common: describe a heart-rate change with reference to specific values from the graph, not a general trend. 10 real questions from 2023 to 2025 papers make up this page. Submitting each answer for instant marking checks whether a labelled vessel or chamber matches the exact structure the mark scheme names.
