The Heart Dissection - Science - Hurumanu

What have we been learning about? We have been learning about the heart and the circulatory system for the past few days. The parts of the heart and their purposes and the circulatory system; their labels and functions. 

Why are we dissecting heart? We are dissecting the heart to find and label the parts of the heart and be able to explain their functions and purposes. 

 What are the parts of the heart?

• Atrium - The atrium is the upper chamber of the heart that receives blood.
• Ventricle - The ventricle is responsible for pumping the blood away from the heart.
• Valves - The purpose of the valves is to move the blood around the body.
• Pulmonary Artery - The right ventricle artery which pumps oxygen to the lungs. 

There were two parts of the heart that we didn't see because it has been cut off. Those parts were the atrium and the veins. 

Why do we need oxygen? We need oxygen because it produces energy which we need for our body to function. 

Enjoy?  I really enjoyed the experiment because I got to find out and see for myself the parts of the circulatory systems and as well as what the insides of the heart look like. It's very educational and knowledgable, you learn a lot of things with dissection of the heart.

This is a 'pig's heart' that has been cut open. We were taught which side (right or left) was bigger. 

The left ventricle was the biggest side of the heart which means the side is where we are going to cut first. We cut it side ways with a sharp dissecting knife. 

As you can see from this image, you can clearly tell that the bigger part of the heart means it's the left ventricle. It had more heart strings. we also saw the artery but it has been removed before so we only got to see the hole.
