Talofa and welcome back to my blog.
Last Friday, in Science, we dissected a Lamb’s Heart. We had to get into pairs, and I went with one of my classmates, Mohammad.
The aim of this was to understand how the heart works and how it keeps us alive. We did this by cutting the right side of the heart with scissors and started to figure out where the different parts were, then we cut the left side and identified the other parts of that side. Some of the parts we found were the right and left atrium. The right atrium’s job is to receive deoxygenated blood from the body through the Vena Cava, then it sends this blood into the right ventricle, which then pumps it to the lungs through the pulmonary artery for oxygenation. The left atrium’s job is to receive oxygenated blood from the lungs through the pulmonary veins, then it sends this blood into the left ventricle, which pumps it through the aorta to supply the rest of the body with oxygen and nutrients. There are many other parts we found, like the pulmonary valve, the aorta, and many more.
In conclusion, the heart is an important and complicated part of the body, which is why we have the ribs protecting it so it doesn’t get hurt.
Here are some pictures and a diagram of the heart.
