Heart Dissection

Hi everyone! Welcome to another post, recently in science we dissected a pig's heart, we did this so that we could learn more about the heart and what it does.

🛈 - Information
The heart is important because, without our heart, the brain wouldn't work. The heart pumps the blood around the body, the blood that it pumps out carries many nutrients and oxygen.

Heart Diagram: A diagram of the parts of the heart. 

• Arteries: Arteries are a blood vessel that takes the blood away from the heart. 
• Veins: The veins take the blood back to the heart.
• Atrium: The Atrium is the upper chamber of the heart that receives blood.
• Ventricle: The ventricle is a V - shapes cavities that push the blood into the arteries to take it away from the heart. 
• Vena Cava: The vena cava is a large vein carrying deoxygenated blood from the body to take to the heart. - Deoxygenated means that it does not carry oxygen. - 
• Aorta: The aorta is the main artery that carries the blood away from the heart to the body. 
• Right Side of Heart: Deoxygenated blood enters the right atrium from a vein called Vena cava, the blood is then pumped to the right ventricle. The right ventricle then pumps it to the lungs to get oxygen 
• Left Side of Heart: Like the right side of the heart blood enters the left atrium but this blood is oxygenated, which means it carries oxygen with it. Then the atrium pumps it to the left ventricle, after that the left ventricle pumps the blood to the body to deliver oxygen. 
• Valves: Valves are gates that only go one way. They open up to let blood flow to the ventricle, it then closes so that blood doesn't flow back out. 
• Heart Strings: The heartstrings are strong fibres that hold the valves in place.  

My opinion: 

I really liked dissecting a heart, it was very fun and I learned a lot of new things about the heart. I especially liked when we cut the side of the heart because it just looked so satisfying and professional.
