THE IMPORTANT FUNCTION OF THE ARTERIES – INTRODUCTION

When I think about the enormous amount of traffic that passes incessantly over the highways leading to and from major cities such as New York or London, I must say that the expression ‘arterial roads’ indeed seems appropriate and justified. If for some reason those traffic arteries were paralysed, life in those large cities would soon come to a standstill. The importance of the ‘arterial roads’ in our bodies, the arteries, will only begin to dawn on us when we study them closely. Even the most attractive human body, with shapely limbs and perfect muscular build, will begin to deteriorate and degenerate, just as the gifted and trained brain will begin to fail, when the walls of the arteries thicken and harden and thus lose their elasticity.

Even the anatomical structure of the arteries tells us a great deal about their importance. Imagine a pipe made up of various layers, the inside being a smooth, elastic tube. This tube is covered with other layers that consist of elastic, or loose but tensile, connective tissue. The tube can withstand a pressure of about 20 atmospheres (1 atmosphere equals 14.72 pounds to the square inch).
