The World's Greatest Distribution Network:
The Circulatory System

Let us imagine a city with 100 trillion households. Do you think there can be a distribution company capable of fulfilling the demands of all the households in this city? Most people would say, "Of course not." However, a similar system already exists in the human body. But the houses in the human body are cells, and the distribution company is the circulatory system with its numerous components.

The components of the circulatory system visit approximately 100 trillion cells in the human body one-by-one. The nucleus of this system is the heart. The heart, which has 4 different lobes pumping fresh and spent blood without mixing them to different regions of the body and with valves functioning as security flaps, has a design established with very delicate balances.

When we examine the heart, we see that it doesn't consist merely of a pump but also of valves that determine the direction of the pumped blood. They ensure that the blood pumped by the heart muscles moves in exactly the right direction. Furthermore, the heart is connected to both lungs and the rest of the body by major blood vessels. The vessel leading to the body separates into branches which, in turn, separate into small branches in a continuing process. This separation goes down to the capillary veins which then expand as larger veins until they return to the heart again. They go to the lungs to rid themselves of the carbon dioxide in the blood and fill up on oxygen instead.

When this circulatory system is examined, which includes the heart, the blood vessels and the lungs, a complex system is revealed. When you add to this the kidneys, which are in charge of cleansing the blood, the pancreas, which adjusts the sugar level in the blood by secretion of insulin or glucagon, the liver, which keeps the chemical content of the blood under control, and the members of the immune system in the blood, a magnificent structure appears. Every piece of this complex system is in harmony and they are connected to each other in a well-arranged way. All these harmonious elements serve a common purpose. If only one piece were absent, defects would occur in the system. This could cause a situation that might end with the death of the person owning this circulatory system.

A heart cannot keep a body alive more than a minute without the lungs that clean the blood which the heart pumps. The circulatory system came into being with all of its parts intact, at a single moment. This, then, shows a perfect design, that is creation, of the heart and the circulatory system and illustrates the matchless creation art of God, the Lord of all worlds.
