HEART DISSECTION!

Yesterday's lesson was an exciting one as we got to dissect a pig's heart! There are different parts of the heart that we have been researching about, The atrium which is the upper chamber of the heart that receives blood, The ventricles which are the bottom parts of the heart which pump the blood out of the heart, The Aorta is the largest artery and takes the blood away from the heart and around the body, The vena cava is a large vein that takes deoxygenated blood that has traveled all around the body to the heart, The valve's job is to stop the backflow of the blood, the valves are attached by the heartstrings wich help the valve's stop the backflow of the blood. To start the dissection we first cut open the right side of the heart which revealed the valves, heartstrings, Arteries, And veins! After that it was kinda a free for all, my group ended up tearing the pig's heart in half to get a better look at what was inside. Our materials only consisted of tweezers, Scalpel, and dissection scissors.  The heart is one of the most important organs in your body, its job is to pump the blood around your body and into your lungs to dispose of carbon dioxide and gather oxygen. Without a heart, we wouldn't be able to survive as we wouldn't get the energy and nutrients that we get from the blood that flows around our bodies. Overall this was really fun and interesting to understand how our own bodies survive!
