During exercise, the heart muscle's oxygen requirements increase significantly to meet the heightened demand for blood flow and energy. As physical activity intensifies, the heart pumps faster and harder, requiring more oxygen to support the working muscles. This increased demand is met by an increase in heart rate and stroke volume, ensuring that sufficient oxygen-rich blood is delivered throughout the body.
