  1. Heart-Walk Presenter: D .Kacher a reinforcement activity

  2. Students will reinforce their knowledge of the heart by walking on a large floor-drawing of a heart and naming its parts. • As they “walk through” the heart, they will follow the pathway of blood through the heart.

  3. Objectives • identify right and left heart • name the chambers, valves, and great vessels associated with both rt. & lf. heart • demonstrate how blood flows through the heart

  4. Teacher materials • 2 strips white butcher paper (approximately 9’ long • clear vinyl tape • pencil with eraser • drawing of the inside of heart heart (coronal plane) • blue, red, & yellow Sharpie markers • scissors • access to laminating machine • 2 sheets of blank printing paper

  5. Teacher preparation • Cut two large strips of white butcher paper (approximately 9’ in length) • Tape strips lengthwise with clear vinyl tape (you should have a large sheet of paper approx 9’ x 6’—depends on width of butcher paper) • Using a pencil, draw a large heart (outline & inside– see template side) • Do NOT label • Outline right heart in blue, left heart in red, & valves in yellow

  6. Teacher preparation cont. • Cut drawing into lengthwise strips so that they will go through a lamination machine. • Using template, draw a large drop of blood on each sheet of print paper. • Color one drop blue & one red. • Laminate and re-tape heart drawing with clear vinyl tape • put sheets of paper with blue & red blood back-to-back and laminate

  7. Template for heart drawing

  8. Here’s how your heart should look once it’s outlined.

  9. You can copy and paste this “blood drop” onto a Word doc, then print 2 of two copies Color one blue & one red. Place drops back-to-back. Laminate

  10. Make a spinner (Can buy blank ones at teacher supply stores. Try to find one with 12 wedges.) Make labels of the following & adhere to spinner: Vena cava Rt. Atrium Tricuspid valve Rt. Ventricle Pulmonary valve Pulmonary arteries Lungs Pulmonary veins Lf. Atrium Mitral valve Lf. Ventricle Aorta

  11. How to begin …and end • Tape Heart-Walk drawing to floor. • Demonstrate how to walk through heart beginning at the superior vena cava • Be sure and have the blue drop of blood facing outwards. • Once you get to the pulmonary artery, step out of the Heart-Walk into the “lungs”. • Turn drop of blood to red side and return to the heart via pulmonary veins. • You are finished when you end up at the SVC.

  12. Example of Heart-Walk drawing

  13. What comes next? • Coronary arteries • Electrical conduction in heart

  14. My favorite handout pictures of coronaries

  15. My favorite handout picture of SA node & electrical conduction

  16. Biomedical engineering & biotechnology as it relates to the cardiovascular system: • Screening technologies –stethoscope, BP, serum cholesterol levels • Diagnostic technologies – EKG, blood enzymes, cardiac catheterization • Interventional technologies – medications, angioplasty, stents • Therapeutic technologies – meds, surgery
