About this worksheet
Year 6 pupils complete a passage on the double circulatory system in this three-page cloze. The word bank has fourteen words: twelve to use, plus skeleton and stomach as spares. The four paragraphs cover the heart as a pump, the atria, ventricles and valves, the trip to the lungs, and the arteries, capillaries and veins. A heart diagram shows the four chambers with arrows for blood flow. Questions 13 and 14 ask for the difference between an artery and a vein, and why the heart beats faster during exercise. The answer key lists every gap and models both answers. It follows the England National Curriculum for animals, including humans.
