Describe the structure and function of red blood cells, white blood cells, plasma andv platelets. Identify the following cell types: B ......................... A ......................... C ......................... Give one function and one adaptation of: white blood cells: .............................................................................................................................................................. .............................................................................................................................................................. red blood cells: .............................................................................................................................................................. .............................................................................................................................................................. platelets: .............................................................................................................................................................. ............................................................................................................................................................. Explain how the structure of the heart is related to its function: the direction of blood flow through the heart. Which of the following shows the direction that blood flows towards, through and from the heart? vena cava → ventricle → atrium → pulmonary vein pulmonary artery → atrium → ventricle → aorta aorta → ventricle → atrium → pulmonary vein pulmonary vein → atrium → ventricle → aorta blood, the heart and circulatory system Explain how the structure of the heart is related to its function: the atria and ventricles Cardiac output is the volume of blood leaving the A atrium every heart beat B atrium every minute C ventricle every heart beat D ventricle every minute Describe the changes that occur to the blood and chambers of the heart during a heartbeat. ..................................................................................................................................................... ..................................................................................................................................................... ..................................................................................................................................................... ..................................................................................................................................................... ..................................................................................................................................................... Explain how the structure of the heart is related to its function: the valves Describe the role of the valve labelled on the diagram. .......................................................................... .......................................................................... .......................................................................... .......................................................................... Explain how the structure of the heart is related to its function: the four major blood vessels How does the blood plasma allow respiration to occur? .............................................................................................................................................................. .............................................................................................................................................................. Where else in the circulatory system would we find valves? .............................................................................................................................................................. Describe the grouping of cells into tissues and tissues into organs and organs into systems. A B C .......................................................................... ............... D Explain how the structure of the heart is related to its function: the difference in size between the right and left-hand sides of the heart Suggest how the blood flowing through the pulmonary artery would be different from the blood flowing through the aorta. Which of the diagrams above shows: A specialised cell .......... A tissue .......... An organ .......... A system .......... Explain what is meant by the term 'tissue'. .............................................................................................................................................................. .............................................................................................................................................................. Use the letters to put the structures into size order. .......................................................................... Use four blue and red coloured arrows to show where deoxygenated and oxygenated blood enter and exit the heart. Label the two missing blood vessels. ..................................................................................................................................................... ..................................................................................................................................................... Which side of the heart is bigger? Explain why this is. ..................................................................................................................................................... ..................................................................................................................................................... ..................................................................................................................................................... Describe how the circulatory system transports substances around the body in terms the structures and functions of arteries, veins and capillaries. Label the images of the blood vessels with their names. For each blood vessel, give at least one feature of its structure and at least one reason for each feature. Outline the overall function of each blood vessel. ..................................................................................................................................................................................................................................................................................................... ..................................................................................................................................................................................................................................................................................................... .....................................................................................................................................................................................................................................................................................................
