    respire faster. Meaning- they need more oxygen and glucose and release more carbon dioxide. A faster breathing rate means that oxygen can be taken into the body at a faster rate and carbon dioxide can be released faster. Cardiac output = stroke volume x heart rate Effects of exercise: Ventilation – breathing Respire – release of energy from food/chemicals Anaerobic respiration … is release of glucose without using oxygen. This produces lactic acid. glucose = lactic acid
