Hello everyone, welcome to my first blog post of Term 2.
In this blog post, I am going to share what we did in science while dissecting a pig’s heart. This was a very interesting activity because it helped us learn more about how the heart works and what it looks like on the inside. During this lesson, we were able to investigate the different parts of the heart and understand how blood moves through it.
The equipment we used included scissors, a pig’s heart, tweezers, and a scalpel. First, we put a newspaper on the table and placed the heart on a tray so that the blood would not get on the table. We also wore lab coats to protect our clothes from getting dirty.
After that, we were each given a heart and had to carefully cut it open in half, like opening a book. Once it was open, we looked closely at the different blood vessels and the structures inside the heart. We tried to identify some of the important parts, such as the chambers, valves, and veins. It was fascinating to see how strong and detailed the heart was.
As the teacher told us to investigate further, we looked more carefully at the inside of the heart and discussed what we noticed. We observed the texture, shape, and different sections of the heart. This helped us understand how the heart pumps blood around the body.
- Left atrium
The left atrium gets blood with oxygen from the lungs and sends it to the left ventricle. - Left ventricle
The left ventricle pumps the oxygen-rich blood to the rest of the body through the aorta. - Right atrium
The right atrium gets blood with less oxygen from the body and passes it to the right ventricle. - Right ventricle
The right ventricle pumps blood with less oxygen to the lungs so it can get more oxygen.
That’s all for this blog post.
