Sheep heart dissection

 Today we are dissecting a sheep's heart. Our aim is to identify the different parts of the heart and to see how it works.  

I think we will see a lot of blood, where the blood flows through, the Septem, veins, arteries, pulmonary, ventricles, atriums, valves.

Method:                                                                          Right side: 

1. From the superior vena cava, cut down the right side from the atrium to the ventricle.

2. Identify the right atrium, ventricle and the valve.

3. Follow from the ventricle up through the artery (pulmonary). Where does it go?

Left side: 

4. From the Pulmonary vein, cut down the left side from the atrium to the ventricle.

5. Identify the left atrium, ventricle and the valves.

6. Follow from the ventricle up through the artery (aorta). Where does it go?

Pulmonary is related/something to do with the lungs.

The septum is the thing that divides the left and right side of the heart.

The heartstrings are strong fibers that hold the valves in place.

When we cut it open we found the heartstrings, ventricles and a lot of tissues outside of it.

In conclusion, we saw a lot of things we expected, it didn't really smell as bad as I thought it would be.

We saw that the left side of the heart is thicker than the right side because the left side needs to pump more blood throughout the body and not just to the lungs.

I found it interesting to dissect a heart, it didn't really smell that bad as I thought it would. I probably wouldn't want to do it again.
