Focus Question: What are the parts of the lungs?
For the my lung presentation, I learned about TB. Tuberculosis was really interesting to me because I did not know there was a latent form and an active form. I also thought it was interesting how only the active form can sread and that it is only spread through the air. I think the part that struck me as most weird was that it can not be spread through sharing food and kissing. I thin kI learned the most about how it is spread. I also learned that the active needs more testing once a person is diagnosed with TB. For example, I did not know that the two tests that were given only detected the presence of TB in a body.
Procedure: The first step for this dissection was cutting two incisions on the day's chest. We were supposed to cut through the costal cartilage so we could remove the sternum. We then cut the cartilage around the trachea. After that, we cut around the posterior lobes of the lungs slowly. We then separated the trachea and the esophagus. After that we made a cut through the superior and inferior vena cavas of the heart. After that, we took out the respiratory organs found in the data/observation section. After that, we looked for the primary, secondary, and tertiary branches.
The incisions are shown below in yellow dotted lines.
Materials Used: In this dissection, we used scapels, teasers, and a microscope.
Data/Observation:
Below is the labeled picture of the lungs and other parts of the respiration system.
Here is a microscopic view of the alveoli. The alveoli are the white circles.
Reflection: There are many parts to the respiratory system that I was unaware of like the larynx. I learned that the lungs are spilt into lobes and that the heart sits in between the lungs as well. I also did not know that the windpipe was the trachea so I thought that was cool. I think my favorite part of the dissection was cutting through the costal cartilage to remove the sternum. I thought that it was really difficult figuring out what to cut around the lungs' lobes when removing it. Overall, I thought it was really interesting to see
