- 26 - PRINCIPLES OF HEALTH AND HYGIENE Human structure is a combination of various elements that include organs, bones, fat and blood. Organs (which include muscles) form 45% of the body’s weight. Principles on Which Your Strength is Dependant There are at least 639 organs in a human body and each organ has the following four characteristics: Every organ is capable of moving and has energy that can be measured. Every organ stores some stock of energy that does not depend on the blood-supply, i. e. some organs can still be used after the ow of blood has stopped. This is known as the capacity of energy storage of an organ. Every organ has the capability to shrink. The healthier the organ, the faster will be the reex to shrink. Every organ is exible and can be stretched. The more the exibility, the better. The combination of the above four characteristics provides the total energy and power to an organ. It is important to note that when the total power of the organ is being used, new and continuous energy supply replaces the depleted power. This replacement is done by the ow of blood in the body. For the blood to be healthy and sufcient for this purpose, the following four conditions apply: Blood should be healthy and free of disease. Arteries should be healthy and pliable. Heart should be strong and healthy. Lungs should be healthy, strong and spacious. 1. 2. 3. 4. 1. 2. 3. 4.
