Respiratory Epithelium: Goblet Cell

Harry Potter and the Goblet of Mucus.
Yesterday, no one came to microanatomy class. I did though, and this is what I kind of learned:

Respiratory epithelium differs based on where you are along the respiratory tract. In the nasal mucosa, you'll find pseudostratified columnar epithelium with the following cells: goblet cells, ciliated cells, and basal cells. Underneath this is a vascularized lamina propria with mucous/serous glands

Goblet cells secrete mucin, ciliated cells beat up all the junk in your airway towards the pharynx, and basal cells are stem cells. 

Down the respiratory tract you'll lose the goblet cells and then you'll see all the cool lung-y stuff. 

Also, I'M TIRED.
