The Dissection of the Heart
Students observed the dissection of the heart and lungs of a sheep, and dissected a sheep heart, as part of the science unit on the circulatory/cardiovascular system. Ms. Salem conducted the dissection.
You may think it’s disgusting, but I thought it was really cool! Some time ago, my teacher thought that it was time to dissect a heart since we had finished studying about the circulatory system. Mrs. Salem, a fifth grade teacher, came to our class and brought in the heart and lungs of a sheep, and she demonstrated how to dissect them!
At first I thought the dissection was really gross, but when I actually waited and saw the rest, it was the coolest thing I had ever seen in my whole life! Every time she opened up something like the heart or the lungs, she would pass it around, and we got to touch it! Like when she opened the heart, we saw what was inside and we saw some veins, and when she opened up the lungs, we saw the vessels and we got to touch them, they were really hard! During the dissection of the lungs, Mrs. Salem showed us how our lungs work. So she got the lungs and blew through the trachea, and suddenly, the lungs inflated! She tried it another time, she blew, and this time they inflated even more!!! Everybody started saying “wow!”and “cool!” I thought that was the best part, but in came the afternoon, when we got back from recess, and there were more hearts on the table! Miss Noshie placed us each in groups of four, and each group got one heart, some gloves, and scissors too because this time, we were going to do the dissection.
What I really hated was when we dissected in groups, because we actually got to do the dissecting, and we saw all the parts, we even had to cut some veins and codettas! What I thought was really disgusting, was when Miss Noshie got the scissors and took out all the de-oxygenated blood. It looked like black jello, even worse, black slime! It was so sticky and disgusting, but still I thought it was kind of cool. The last thing I thought was really something not cool was the smell. I really thought that the heart smelled horridness and really stinky, especially the blood!
I really thought the dissection was cool; I can’t wait to dissect the brain! I think it would be way cooler since its one of the most important organ in our body. But I don’t want to be a doctor because I have to do dissect things that I really don’t want to see!
