The student describes their group's project on the human body in school. Their teacher assigned them to a group and their project was on the human body. They first had to build a skeleton model and then got to look at and touch a pig's brain, which the student found gross. Next, they examined a pig's heart, which was slimy, bloody and felt weird. The passage also provides some brief facts about cells fitting on a period, the inside of bones being spongy, and the smallest bone being in the ear called the stirip.
