Imagine you’ve been shrunk down to the size of a red blood cell and injected into Kim's bloodstream. Describe, in order, the blood vessel types, parts of the heart, and any other important circulatory system features you’ll be passing through.
Use the following terms correctly: vein, artery, atrium, ventricle, alveoli, capillary, oxygen, carbon dioxide, red blood cell, hemoglobin, aorta, valve. Make sure that you explain the function or importance of each of the items on this list!
Note when the blood would be blue in color and when it would be red, and why. Start your journey in the right atrium and make sure you explain both circuits - lungs and body.
Example: “I’m in the right atrium of the heart, surrounded by red blood cells. But none of them are red right now - they’re all blue, because they’re not carrying oxygen. There's a lot of dissolved carbon dioxide in the blood around me. After a second, the muscular walls of the atrium squeeze in on us, so we’re all pumped through the heart valve into the right ventricle. As soon as we’re through, the valve closes behind us so we can’t go back.”
The attached grading rubric must be attached to your assignment when you turn it in, or I won’t grade it!
