Learners complete sentence stems about pumping blood around the body, higher pressure in arteries, and one-way movement through valves, then map terminology onto a labelled heart diagram. Additional tasks compare the cardiac cycle in humans and structural differences between fish and human hearts, including why the left ventricle has a thicker wall.","Chapter 3: Moving and changing materials  \nExploring the heart: Worksheet 3.13  \n1 The function of the heart  \nComplete the sentences.  \nThe function of the heart is to pump ................................ .......... around the body.  \nThe right side of the heart pumps blood to the ................................ ........ .  \nThe left side of the heart pumps blood to the rest of the ................................ ...... .
