Learning About
How are the heart and the lungs adapted to circulate oxygen and carbon dioxide around the body?
Keywords:
  • Ventricles: Lower chambers of the heart that pump the blood out of the heart. (1)
  • Atria: Upper chambers of the heart that collect blood. (1)
  • Double Circulatory System: A double loop circulatory system has 2 loops with oxygen-poor blood and oxygen-rich blood, that don't mix. (1)
  • Exchange Surface: Specially adapted part of an organism for the movement of chemicals across it, often to and from the blood. (1)

Students should know the structure and functioning of the human heart and lungs What is the structure and function of each of the following: a) heart, b) lungs?

Pluck dissection
how lungs are adapted for gaseous exchange. How are lungs adapted for gaseous exchange?

Describe the movement of gases from the air to the blood. Explain the ways in which the lungs are adapted for rapid gas exchange with the blood. GF: Compare and contrast the structure and function of lungs to the gills.
The heart is an organ that pumps blood around the body in a double circulatory system. How is blood pumped around the body in the human circulatory system?
The right ventricle pumps blood to the lungs where gas exchange takes place. The left ventricle pumps blood around the rest of the body. Where does the left ventricle pump blood to and where does the right ventricle pump to?

Heart Dissection
Knowledge of the blood vessels associated with the heart is limited to the aorta, vena cava, pulmonary artery, pulmonary vein and coronary arteries. Knowledge of the names of the heart valves is not required. What are the names and functions of the blood vessels in the heart?

Describe the movement of the blood from the lungs to the heart, around the body and back to the lungs. Explain the advantages of having a double circulatory system compared to a single circulatory system. Explain why the left ventricle muscle is larger than the right ventricle.
Knowledge of the lungs is restricted to the trachea, bronchi, alveoli and the capillary network surrounding the alveoli. What are the names and functions of the main structures in the lungs?
The natural resting heart rate is controlled by a group of cells located in the right atrium that act as a pacemaker. What controls the natural resting heart rate?
Artificial pacemakers are electrical devices used to correct irregularities in the heart rate. What are artificial pacemakers?

Explain how an artificial pacemaker keeps someone alive.
