Four-Chambered Heart – “The Plumber” In this project you will explore the circulatory subsystem within the heart by building a model of the human four-chambered heart. In addition to the biology concepts, you have an opportunity to build electrical circuits and use coding to write a program that blinks four LEDs in the order of the ...

Build a model of the four-chambered heart’s electrical system. Your model should be similar to the one used in The Plumber, but the wiring is different. Be sure to insulate the upper from the lower heart using a piece of paper. The paper functions similarly to the non-conducting collagen fibers in the cardiac skeleton.

The human heart is a four-chambered structure designed to pump blood in specific directions. To understand how the heart functions (and sadly, malfunctions), you must first understand the actual physical structure and organization of this amazing organ. Cells in your body combine to form tissues. Tissues combine to form organs such as the heart.

Birds have a four-chambered heart and two circulatory loops. A bird’s heart has two separate ventricles. Oxygen-rich blood and oxygen-poor blood are completely separated. Birds have an excretory system similar to that of reptiles. Nitrogenous wastes are converted to uric acid and sent to the cloaca.
