Organs and Organ Systems

Blood and Guts Galen lived from AD 129 to 216 in Rome He was a doctor to the gladiators and eventually became the emperor’s doctor While he was trying to heal their open wounds, he observed their internal organs

Blood and Guts Because they bled so much he observed how blood flowed in the body. Some of his ideas were bizarre: he thought the liver was the most important structure in the body because it was so big and had lots of tubes.

Organs Activity What do you know about the body’s internal and external parts and how they work together? In groups of 2-3 make a list of all the body parts that you can think of, both internal and external. Write each one on a post-it. Try to figure out how they work together to keep you alive. Once your group has decided the pattern, create a concept map showing how the body parts are linked.
