About thirty Carthage Junior High students took part in a walkthrough of the circulatory system on Friday.

The students, from Mrs. Jeanie White and Mrs. Kacey Thayer’s science classes, played the roles of red blood cells moving through the arteries and veins of the body and the chambers of the heart.

As they moved they denoted what vital role they were playing, whether it was carrying oxygen throughout the body or carrying carbon dioxide back to the lungs.

Afterward, Thayer presented a pig’s heart and lungs to the class for inspection, while describing further the act of circulation in the body. 

The organs were only partially unfrozen. She had set them out to thaw the day before, but they apparently needed a bit more time.

“I should’ve given it two days to thaw,” she said.
