Answer:
esophagus has stratified squamous
Explanation:
Stratified squamous is a tissue that is found covering and lining parts of the body such as the esophagus. It is known to be many layers of flattened cells.
It performs some functions like the provision of protection from abrasion, pathogens, and chemicals.
It can be found in some parts of the body like surface of skin, linings of mouth, esophagus, rectum,and vagina.
In this case, the presence of stratified squamous in a slide will definitely show that the content in the slide is esophagus. And the slides can then be easily separated and labelled accordingly.
