Did you look forward to biology dissections in school, or were you as far away from the sample as possible with a hand clasped to your mouth? Recently the Avasara Leadership Fellows experienced dissection for the first time, when the 10th Standard studied breathing and respiration. We began with some explanations and theory, and then got hold of a pair of goat lungs to examine!
First, those girls who were willing to touch the lungs got the chance to hold them, feel their sponginess, and feel the cartilage in the trachea and the bronchi. The lungs seemed very flat to begin with, and it was hard to imagine them in action. The girls were then provided with straws that they could insert into the trachea to see if we could inflate the lungs.
After several attempts from very willing volunteers we realised that we could inflate the lungs to over double their original size!
Inflating the lungs was a lot of fun, but cutting them up gave us the chance to examine internal structures like bronchi and bronchioles.
We’re already looking forward to our next dissection…
