Cardiovascular/Respiratory connections:

  1. Discuss the intricate relationship between the cardiovascular system and the respiratory system that occurs at the lungs. Why is this significant to the function?
  2. Predict the purpose for the large number of blood vessels in the lungs. What purpose does this serve?

Thoracic Cavity:

Gently pull and push the knob at the base of this model and observe what is happening.

  1. What relationship exists between volume and pressure in this “thoracic cavity?” What role does the diaphragm play in this relationship?
  2. Diagram the position of the diaphragm during “inhale” vs. “exhale.”
  3. Predict other anatomical structures that may assist in the process of ventilation.

Asthma Model:

  1. Predict the tissue layer of the bronchi that is affected by a) constriction and b) inflammation due to asthma.
  2. Discuss two ways this model demonstrates the relationship between the respiratory and lymphatic systems.

Pig Lung Demonstration:

Inflate the pig lungs with the pump by gently pumping the bellows. Please do not over inflate. Observe the lungs carefully.

  1. How are the lungs like and unlike balloons?
  2. What are the factors that contribute to lung capacity and volume?
  3. Look carefully at the lungs as air is pumped in. Discuss your observations in terms of where the air appears to go within the lungs.
