Girl running

When we exercise, the heart works extra hard to pump blood to the lungs to pick up oxygen and then throughout the body to bring oxgyen and glucose to the cells for cellular respiration (a process to make the energy we need to exercise). Glucose is brought to the body, first by digestion and absorption of the food we eat, and then by circulation of the glucose via the circulatory system to the cells of the body.
