The elastic properties of the arteries are essential for blood flow. Explain the importance of this in terms of the characteristics of the flow of blood (pulsating or continuous).

The arteries and the lungs should be very stretchable. The elastic properties of arteries are essential for the blood flow. It is known that the heart pumps the blood and moves from arteries to the whole body. Now, when the blood is drawn out of the heart, it increases the pressure in the arteries due to this; the arteries stretch to maintain the smooth flow of the blood. As we feel the pulses, it is due to the elastic behavior of the arteries. In each pump of the heart, the blood rapidly flows in the arteries; that is the reason pulse can be felt. If the arteries do not have the property of elasticity, then it is not possible to feel the pulses.
