Activity 4.3.3: Go With the Flow Introduction Arteries flow away from the heart and branch into smaller vessels called arterioles . These arterioles lead into the capillary beds, thin nets of vessels where gas exchange occurs. Blood then converges back into small veins called venules and eventually back into the major veins to be returned to the heart. Vessel size varies dramatically along this path. The aorta, the largest artery in the body is almost the diameter of a garden hose. The capillaries, on the other hand, are so tiny that about ten of them would be as thick as one of the hairs on your head. You have looked at the structural differences between arteries and veins. Now you will “get the blood pumping” by creating circulatory routes on your Maniken ® . You will follow the steps to create the blood vessels that service the arm and the neck and then you will work independently to bring blood to and from other parts of the body. As you create each branch, think about how these vessels bring needed oxygen and nutrients to the tissue and how they remove harmful waste. Equipment Computer with Internet access Anatomy in Clay ® Maniken ® Pink and blue clay Red and blue marker or colored pencil Clay extruder Wire tool or wooden knife Tape flags Body system graphic organizer Skeletal system graphic organizer Laboratory journal Meter stick (optional) Reference textbooks (optional) Procedure This activity is a modification of activities in Section H of Starla on Maniken ® produced by Zahourek Systems, Inc. and is used with permission. Refer to Starla on Maniken ® for helpful graphics and for additional ideas. Part I: Arteries In Part I of this activity, you will follow directions to build arteries of the neck and arms on your Maniken ® . You will then build additional arteries independently. 1.

Use the clay extruder to create long strands of spaghetti using pink clay. Lay the long strands over the edge of your desk or over a meter stick. Your teacher may do this for you in advance. 3. Your group should pair with another group to form a team of four. Create vessels on your own Maniken ® , but work with your team to discuss and debate placement. 4. Label each artery you build on the model with a tape flag. Artery names are listed in bold in the directions that follow. 5. Find a web page or a textbook page that clearly illustrates the arteries of the arm and neck. Keep this reference handy as you build on your Maniken ® . The directions will be easier to follow if you refer back to the illustration.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
