Part 1: From the Heart
What structures make up the circulatory system in humans?
What role does the heart play in the circulatory system?
How does the heart's structure help it do its job?
What role does each type of branching blood vessel -- artery, capillary, and vein -- serve?
How does the structure of each type of blood vessel relate to its function?
Part 2: Map of the Human Heart
Make a labeled drawing of the heart and show the pathway of blood (arrows) from when it enters
the right side of the heart until it delivers oxygen to the rest of the body. Use a red and a blue colored
pencil or highlighter for the arrows to show blood with oxygen vs without oxygen.
Describe the different pumping jobs of the two sides of the heart (Step Thru)
How do you take your pulse?
How much blood is in your body?
What is the largest artery in your body?
What’s the size of your heart?
Where is your heart? Describe its location
Part 3: Heart Transplant
What are some reasons why a person might need a heart transplant?
Where do you think donor hearts come from?
Because human donor hearts are so scarce, doctors have recently begun investigating the
possibility of using hearts from different species for transplants in humans. Why might this be
problematic?
Part 4: Artificial Hearts
What structures would need to be included in the design of an artificial heart to enable it to
function like a human heart?
