A scientist by the name of Francis Arthur Bainbridge reported this reflex in 1915 when he was experimenting on dogs. Bainbridge found that infusing blood or saline into the animal increased heart rate. This phenomenon occurred even if arterial blood pressure did not increase.
Blood Flow. Rising carbon dioxide levels and oxygen demands force your heart to contract more frequently, which increases your heart rate during exercise. Blood flow increases as your heart pumps more oxygen and nutrients through your circulatory system's systemic portion. The systemic circulatory system includes blood vessels that deliver oxygen and nutrient-rich blood to tissues throughout your body.
