questions:
2. Real live lungs are different than the model because one there is no bronchi , bronchiolis or avoli in the demonstration. 2 . the size of the thoracic cavity and the lung is disproportionate. As well two lungs are contained in the thoracic cavity. 3. there is no intercontinental mussels shown.
3. The general mechanism of the lungs is displayed in this model as it expresses the fact that air does not get blown into our lungs , but it is the diaphragms movements. When the diaphragm is contracting air is being blown out of our lungs due to less space when the diaphragm is expanding air goes into the lungs due to more space.
