Sri Satguru Jagjit Singh Ji eLibrary [email protected] . Finding out The process of finding out how the incredibly complex human body works started thousands of years ago—long before there were medical schools and devices that enabled doctors to look inside the body. Even today, thanks to huge SS CC II advances in technology, we are still making new SS AA BB discoveries about the workings of the body. YY DD OO BB ◀ CANOPIC JARS The ancient Egyptians placed body organs in stone or ceramic vessels known as canopic jars. There was a different jar for each of four main organs—the lungs, stomach, liver, and intestines. ANCIENT WISDOM Many ancient cultures contributed towards a greater understanding of how the body works. The Egyptians, for example, realized that the heart was at the center of a system that drove the blood and that the pulse was related to the heartbeat. They also gained some knowledge about the body’s internal organs during a process called mummification. This involved removing the major organs of the dead and preserving them in jars placed alongside the body in the tomb. GLADIATORS’ DOCTOR Claudius Galen was an important Roman-Greek surgeon and philosopher. In the early 160s ce, he was put in charge of treating wounded gladiators. As a result, Galen learned much about the human body and although many of his ideas were wrong, he discovered that arteries carried blood and that urine was made in the kidneys. ◀ ROMAN MOSAIC In ancient Rome, gladiators fought to the death, inflicting horrific wounds on each other. 8 .
