Kieran’s school was closed today, so we dissected a pig’s heart. We’d been looking at diagrams of the heart, but trying to find structures on a real heart was much more challenging! At last we found and opened all four chambers. We used a wooden probe to follow the blood flow from the vena cava into the heart, through the chambers, and out again through the aorta. A good day for science!
