Begin the lesson by showing the screen that appears titled, "Map of the human
heart.: The numbers on the side of the page correspond with the pumping heart on the
right. As each number appears on the right, read the corresponding number on the left.
Scroll down to the bottom of the page where the cross-section of the heart appears. Point
out the major parts of the heart (right pulmonary vein. Right atrium, left pulmonary vein,
left atrium). Again, explain verbally, the pathway of the heart (right atrium, right
ventricle, lungs, left ventricle, left ventricle, body).
Scroll down to the very bottom of the page and click on the icon called troubled heart.
A picture of a coronary artery will appear. Read the caption below the picture. Scroll
down to the second picture of the cross-section of the coronary artery affected by
arthrosceloerosis (hardening of the arteries). Read the caption below the picture. Show
the next three pictures of the heart and read the captions below them.
Look at the amazing heart sheet and read the first bullet. Have the students
participate in recording their heart rate. Then help the students find their pulse by
having them place their fingers on their neck looking for the carotid artery. Have them
take their pulse for ten seconds. Then help them multiply this number by 6 to find their
heart rates for one minute.
