![]() This comes from the two pairs of valves in the chambers of the heart. This has to do with the fact that our heart has four chambers, which we'll get too soon. ![]() What does your heart sound like? How fast is it beating? What's the pattern?Ī few students may be able to detect the WUMP-wump, WUMP-wump part of the beat (which they've probably heard in movies, too). You can do the radial artery (inside the wrist), the carotid artery (on the neck), or simply feel your chest. A way I help students remember is that the heart thinks it's the most important organ in the body, so everything going to it is a "vein" because it's "vain." To feel our pulse, check one of the easy arteries and hold for 30 seconds. We describe the tracks as veins (blood going to heart) and arteries (blood going away). For review, point students to this page: 'The Ultimate Pig Dissection Review' which contains diagrams, gallery photos and links to practice quizzes. It makes for a good reference and study guide. Cut the pig open, and identify what organs you can using page 21 (of importance: lungs, heart, diaphragm, stomach, kidney, liver, intestines, larynx, trachea). The circulatory system is one big loop with many branches. Also print out the Fetal pig lab guide - this just lists all of the structures they need to find with a checkbox. After 30 seconds of hopping around, it's time to check those arteries for a pulse. As your body needs more oxygen to its muscles, the heart beats faster to circulate it. The first thing to do is get moving to put that heart into high gear. But whatever it is, feel it out with your classroom or audience.Ĭheck to see if those tickers are ticking! There will always be some students who wish not to do a dissection, and we always allow whatever level of participation they choose in these experiences. For us, we believe that with careful scientific exploration of animals who were treated in humane ways, we can learn and teach our students to be greater stewards of the environment, and especially toward the species they just learned about. One heart (pig, cow, or sheep from the butcher as in tact as possible) ĭissecting animal organisms is a tricky subject which ultimately some will object to and that's okay.There our other dissection photos out there, but I wanted to make a clear walkthrough for teachers and students who are doing it. ![]() A heart dissection is a fascinating experience that is at the core of our circulatory system, and our body as a whole. You've seen them on holiday cards, but now it's time for the real thing. Lab Overview: The tissues, organs, and organ systems of a fetal pig are similar in both structure and function to those found in humans. The original pump that is the drumbeat of our lives is an amazing structure. ![]()
