The reaction of the cardiovascular system to the dosed load?

With a dosed load exerted on the human heart, it can respond with a change in blood pressure. In the process of a dosed load, the rate of contraction of the human heart increases. The number of heartbeats at rest is much lower than during physical activity. After the end of the load, the heart rate returns to normal for some time. The heart can respond to exercise with a rise and fall in blood pressure, a rise in systolic pressure, and a moderate fall in diastolic pressure.
