Right so let's break the first task down; what is happening to her circulatory systemfirst of all.
When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the FOOD to produce ENERGY) more faster than they would normally, so the demand for OXYGEN and GLUCOSE is increased.
Because the muscles are performing cellular RESPIRATION quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their C02 (products of cellular respiration are CARBON DIOXIDE and WATER) so the HEART is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.
Right now the next part of the task asks what is happening to her breathing system (aka respiratory system).
This relates to the explanation I gave earlier; the requirement for oxygen is increased so now the respiratory system (in particular the LUNGS) have to work harder and faster to take in more oxygen and to exhale more C02, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of DIFFUSION is increased.
Oh and for the diagrams you could draw a picture of a girl playing football, then next to that have a picture of her lungs and heart (including the arteries/veins) and show how they are working harder during exercise.
Your heart rate will increase, you will sweat, you will breathe harder, you (might get a stitch), your muscles ache and you become hungry
