One layer of tall and thin cells that looks like it is two or more layers
27
What is one layer of flat cells?
Simple Squamous
28
What is one layer of box-like cells?
Simple Cuboidal
29
What is one layer of tall and thin cells?
Simple Columnar
30
What is two or more layers of flat cells?
Stratified Squamous
31
What is two or more layers of box-like cells?
Stratified Cuboidal
32
What is two or more layers of tall and thin cells?
Stratified Columnar
33
What appears to be two or more layers of tall and thin cells, but is actually only one?
Pseudostratified Columnar
34
Why is Simple Squamous good for lining the lungs and blood vessels?
It is one layer of thin cells, so gases can easily pass through them
35
What Epithelial Tissue is best for lining the lungs and blood vessels?
Simple Squamous
36
Why is Simple Cuboidal good for lining the kidneys?
They are good at absorbing substances, and kidneys absorb a lot of water
37
What Epithelial Tissue is best for lining the kidneys?
Simple Cuboidal
38
Why is Simple Columnar good for lining the intestines?
They are good at absorbing mucus, which the stomach creates a lot of
39
What Epithelial Tissue is best for lining the intestines?
Simple Columnar
40
Why is Stratified Squamous good for lining the skin, mouth, esophagus, and vagina?
It has many thin layers, which means it is good for high-abrasion areas
41
What Epithelial Tissue is best for lining the skin, mouth, esophagus, and vagina?
Stratified Squamous
42
What 2 Epithelial Tissues are extremely rare?
Stratified Cuboidal and Stratified Columnar
43
What Epithelial Tissue is best for larger glands, like sweat glands?
Stratified Cuboidal
44
What Epithelial Tissue is best for the pharynx?
Stratified Columnar
45
Why is Pseudostratified Columnar good for lining the trachea and fallopian tubes?
It secretes substances, but also pushes away substances, which is helpful for moving dust in the trachea and eggs in the fallopian tubes
46
What Epithelial Tissue is best for lining the trachea and fallopian tubes?
Pseudostratified Columnar
