Here's a picture of the freeze-dried human lung you saw in lab. The trachea is visible at the top of the picture. Click on the picture to see it full size.

This image shows the plastic lung model that you viewed in lab. You should be able to identify the thyroid and cricoid cartilages, the trachea, and tracheal cartilages. Click on the image for a larger version.

This shows a close up of the larynx model after it has been removed from the lung model.

This shows the larynx model that has been opened up to see the internal structures. Click here for a labeled picture.

This is a picture of the larynx model. You should be able to identify the epiglottis, the thyroid cartilage, the cricoid cartilage, the trachea, and tracheal cartilage.

This is the larynx model viewed from the posterior side. The epiglottis and vocal folds are visible in this view.

This is a picture showing the dissected sheep larynx. You should be able to identify the epiglottis, thyroid and cricoid cartilages, and the false and true vocal folds. Click here for a labeled image.

This image shows the plastic lung model that you viewed in lab. You should be able to identify the thyroid and cricoid cartilages, the trachea, tracheal cartilages, and secondary bronchi. Click on the image for a larger version.

This image shows the sheep lung preparation. At the top right of the image you can see the trachea. The sectioned lung is at the left. You should be able to identify the secondary bronchus and some bronchioles. Click on the image to view the full image.

This image is looking down the sectioned trachea. You can see the primary bronchi. You can also see pulmonary vessels (you can tell the arteries and veins apart by looking at the preparations with a heart and seeing which portion of the heart the vessels enter).

This picture shows the heart and lung arranged so you can see the pulmonary artery. Click here for a labeled image.

This picture shows the heart and lung arranged so you can see the pulmonary vein. Click here for a labeled image.
