5th graders learn about organs of the body through dissection
5th graders in Mr. Johnson’s science class have been studying the organs of the body. Recently they had the chance to dissect a pig heart to learn more about its function and identify the parts. Before cutting, they had to locate the right and left auricles, vena cava, pulmonary artery and vein, aorta, and interventricular sulcus. Their first cut was through the septum and then a second cut to remove the septum. With the septum removed they could see the inner most parts such as the chordae tendinae, left atrioventricular valve, and semilunar valve of the aorta. They carefully explored with their group and asked questions along the way with Mr. Johnson as their guide. Next up in class they will learn about and dissect the brain of a sheep.
