Kia Ora and welcome back to my blog today I will be talking to yous about what my class and I did for Biology. Today for Biology we dissected a sheep heart.
The first thing we did was we got all the tools and trays that we needed. We needed 3 tools a scalpel, tweezers, and a pair of scissors we also got one metal tray. Once we got everything we needed we then started to cut the heart, we started on the left side of the heart and looked inside. We then cut the right side of the heart and had a look. Once we cut both sides of the heart we then cut the heart down the middle/cut it in half.
When we were cutting up the heart we got to see that the heart had a thin layer of muscle (left) and the other side was a thick layer of muscle (right). After we seen the difference between the muscle we also saw the Valves on both sides of the heart I know they were valves because they are shaped like triangles and a nearly clear with no blood running through them.
We also saw the arteries of the heart there was more then 2 of the arteries that we saw. I knew they were arteries because they were tubed shaped at the the top of the heart.
Here are some photos of the heart that we cut:..
I think that it was disgusting but I still really enjoyed it.
I hoped you enjoyed reading my blog, BYE!!!
