Wall of Trachea- lumen (right), mucosa (ciliated pseudostrat columnar ep w goblet cells), submucosa ( white layer, red splotchy (tubules + ducts that are part of the glands), white layer), adventitia (dense ct) with it's hyaline cartilage (NEVER IN WALL OF ESOPHAGUS), in esophagus would be muscularis externa (smooth muscle)
Mucosa of last slide- lumen (right), ciliated pseudostrat columnar ep with goblet cells, basement membrane that they are sitting on (whitish stain)
Mucosa of last slide- lumen (right), ciliated pseudostrat columnar ep with goblet cells, basement membrane that they are sitting on (whitish stain)
Lung Tissue- alveolar sacs, alveolar ducts, arteriole (bottom leftish center) with smooth muscle + blood cells in it
Alveoli individ to show caps (hard to find)
Human lung- alveoli (right side), upper tube blood vessel, layers of smooth muscle + simp squam ep around it, lower tube is bronchial (lined with respiratory epith: cuboidal or columnar)
