The Heart

 Today we will be dissecting a sheep's heart with my class.

We're doing this dissection  because we want to know how a heart works and what's about it.

My hypothesis is that what we can see and what is inside like the artery, the two atrium, and the valves.

 The interesting part was how it felt,the smell, and how it would. My group and I cut part by part, first we cut up the right part of the heart where the blood is held. After we cut up the whole heart.

When it opened up we saw white strings that held the heart together which is called the heart strings.

Then we investigated the inside of the heart. We tried holding and moving the heart strings.but it held through. The heart strings help the heart not to explode or not to break the part of the heart.

We also saw lots of other things like the atrium and the vertical and we can't forget the valves.

And at the end we cut the internal heart. It was a really big muscle substance.

so at the end of the session i felt really fascinated and grossed out at the same time
