Internal Transport and Gas Exchange · Semester 1

The Heart: Pumping Mechanism

Students will investigate the structure of the heart and its role as a double pump in the circulatory system.

Key Questions

  1. How does the double circulatory system enhance the efficiency of oxygen delivery to tissues?
  2. Explain the sequence of blood flow through the chambers of the heart and associated vessels.
  3. Predict the consequences of structural defects in the heart on blood circulation.
