The slide is very nice and clean. They came super fast in the mail, in a nice little safe box. It doesn't look like the picture, but you can easily identify the pseudo stratified ciliates columnar cells, the goblet cells, the lamina propria, glands, lots of hyaline cartilage, and in some parts some smooth muscle, which is the only challenge because was it tear off the other structures and is not as clean cut as the other structures, for a student like me it would be question time... But if you are comfortable with your histology it should be pretty easy...
The slide was a good quality view of cross section of the trachea.
