Lesson 2: The Biological Pump (Heart Anatomy & Cycle)
Duration of Days: 4
Lesson Objective
Model blood flow through the heart.
How does the heart control flow
What causes heart sounds
Atrium, ventricle, valves, SA node, systole, diastole
HS-LS1-2
Sequencing processes
Trace blood flow
Connect structure to function
Purpose is understanding heart mechanics
DOK 3
AED use
Both sides of heart do same job
Dissection or virtual models
