The Year 12 Biology students are continuing to learn about mammalian body systems. As part of this, they dissected lungs in order to investigate adaptations for gas exchange.

We noticed that the lung tissue contains air, and so it floats, compared to muscle tissue, which sinks.  We could also observe the cartilage rings, which give structure to the trachea.  Mr Prasad inflated the lungs to demonstrate how air fills the alveoli for gas exchange.

Cameron particularly enjoyed learning about what the different parts of the lungs feel like and why they are important.
