34
Q

Why is Simple Squamous good for lining the lungs and blood vessels?

A

A

Simple Cuboidal

38
Q

Why is Simple Columnar good for lining the intestines?

A

Simple Columnar

40
Q

Why is Stratified Squamous good for lining the skin, mouth, esophagus, and vagina?

A

Stratified Squamous

42
Q

What 2 Epithelial Tissues are extremely rare?

44
Q

What Epithelial Tissue is best for the pharynx?

A

Stratified Columnar

45
Q

Why is Pseudostratified Columnar good for lining the trachea and fallopian tubes?

A

It secretes substances, but also pushes away substances, which is helpful for moving dust in the trachea and eggs in the fallopian tubes
