Honors Biology students dissected pigs’ hearts during their cardiology unit on Wednesday and Thursday.
Pairs of students used dissection kits with scalpels, probes, scissor, and pins to dissect the hearts. They identified structures like the aorta, arteries/veins, ventricles, atriums, atrioventricular valves, septum and semi-lunar valves, enabling them to see the anatomy of the hear they are studying up-close.
For Honors Biology teacher Eric Johnson, the pig heart dissection lab is their favorite because students being able to see and interact with structures they’ve learned about in class gives them a new level of context for the unit.
“We’re in our cardiovascular unit, so we are talking all about the heart, we’re talking all about the lungs, the respiratory system, the circulatory system, the blood,” Johnson said. “You can stare at a diagram. It’s not getting the same detail as if you were looking inside of a pig heart, so that’s what we did this way.”
Junior Anika Basu felt that the lab put the lessons she learned this year in context. By supplementing the class’ lectures and presentations, the dissection gives a more realistic, detailed perspective on class material.
“This was definitely one of my favorite labs we’ve done, because it really translates what we’ve learned theoretically and on PowerPoints to real life,” Anika said. “We were able to see the different parts of the heart and the respiratory system that we were learning about.”
The pig hearts were purchased from Lion Market on Saratoga Avenue. Because of their anatomical similarities to human hearts, like having four chambers and a similar vascular layout, pig hearts are a common choice for lab dissections. Students were also given the choice to opt out and do a virtual heart dissection.
Junior Ethan Gu believes the real-life dissection made viewing different structures much easier, which helped improve the learning experience.

“Just getting to feel the heart and cut through it was quite the experience,” Ethan said. “Everything was just tissue and muscle and like the heart is already so big. So it was easy to find the individual compartments and examine them without needing a lot of precision.”
Beyond supplementing class material, the lab is memorable for many students because it reveals the connection between biology and human life.
“When we get to human physiology, our labs become really connected to my students. We make sense of things like the heartbeat,” said Johnson. “I have a small heart condition, so when I study the heart, I relate back to my own experience with my heart condition. There’s something about studying human health, where it’s just an easy connection to your life.”





![“I wasn't discouraged by some of the obstacles we faced. I learned a lot from the leadership. I found that different people need different ways of receiving feedback — you can't [just] tell them to do something and expect the best. [Some] people needed more incentive. A large part of my role was to figure out what worked for everyone and to figure out how to lead all these separate individuals as a team,” Suhana Bhandare (’26) said.](https://harkeraquila.com/wp-content/uploads/2026/06/SuhanaBhandare_JasmineHansra-1-1200x798.jpg)
