Pumping blood is the chief and only function of the heart! Freshly oxygenated blood from the lungs enter the heart which is then pumped out to the rest of the body. After delivering oxygen to all tissues, the de-oxygenated blood returns to the heart, which the heart sends back to the lungs to get re-charged with oxygen. After this, kids are asked to draw a diagram of the heart. But nothing compares to seeing actual heart, with an opportunity to dissect and check how valves are connected and where arteries enter heart from. Given below are snap shot of a lab activity where a real heart of a goat is shown to the students. Each student gets to check the inside of the organ and make notes for the next class.
