Activity 4B: Clumps and Bumps: A Look at Atherosclerosis

This activity features actual photomicrographs of coronary artery disease in young people aged 18 – 24 years of age. Students will observe the image of coronary artery cross sections and use a unit square grid to estimate the amount of open space (lumen), available for blood flow. They will notice the lumen in some of the blood vessels has been reduced as a result of atherosclerosis. Students will then infer what might happen to the heart muscle supplied by these arteries. This activity will provide student background information for a more in-depth study of the development of atherosclerosis.

Objectives: 
  • Label the parts of a typical artery
  • Observe the effects of atherosclerosis on the coronary artery lumen
  • Infer the effects of atherosclerosis on blood flow
  • Describe what may happen when blood flow to specific parts of the body is restricted
