Today we were looking at the heart and we found our way in through the aorta and the pulmonary artery. The hearts were a different shape to what some of us thought they would be. We felt the hearts and they are made of tissue and muscle. We could see the blood vessels. There was some fat on the outside of the heart because we need some fat in our bodies to keep our organs warm and protect them.
Before we cut them we had to feel them to see which side was the thin side and which was thicker. The thicker side was the ventricle muscle. When we cut the hearts open we could see the blood vessels, the 4 chambers and what we think was the aortic valve. We put our fingers through the aorta and pulmonary artery to see which chamber they went into.
Here’s what we thought about today’s dissection:
It was disgusting but extraordinary to see what was inside our heart.
It was interesting to see what the chambers in our heart look like.
I liked it because I found out that one side of your heart is thinner than the other.
The best part for me was feeling the heart because it felt firm, fleshy, strong and slimy.
I liked the part when we saw all the blood vessels because it was satisfying to see what they looked like.
I expected the heart to be a bit bigger because it pumps in your body.
I didn’t know that the fat around the heart was so hard.
It’s interesting how the heart works hard every day and I saw how the blood gets into the chambers.
I enjoyed looking inside the heart because it was amazing to see lots of blood vessels.
I didn’t like the bit when I touched the heart and it was extremely light.
