Summary Introduction

To determine:

The reason behind the unidirectional flow of the blood in arteries as compared to the veins.

Introduction:

The blood flow in the circulatory system is due to the blood pressure. The blood pressure in the arteries is higher than that in the veins. The reason behind the high blood pressure in the arteries is due to the pressure developed by the muscle contraction to pump the blood. The pressure in the veins is comparatively low as compared to the arteries. Therefore, there is the possibility for the backflow of the blood in the veins. This backflow is prevented by the closing of the valves.
