Basement membrane

Question 20

Answer 20

Simple cuboidal

Kidney

Question 21

Epithelium that is responsible for absorption and/or secretion of relatively few, or relatively simple, nutrients, solutes, hormones, etc.

Answer 21

Question 22

Where is this type of epithelium found and how do its structural features help with its function?

Answer 22

Pseudostratified ciliated columnar

Upper respiratory including trachea

Question 23

Name the epithelium

Answer 23

Simple cuboidal

Question 24

Describe clinical effects of thickening or thinning/destruction of the indicated structure (darkest blue) in this tissue type, as well as some causes.

Answer 24

Thinning/destruction: excess solutes, protein, blood in urine (depending on severity); causes: hyperglycemia, hypertension, autoimmune glomerulonephritis, lupus, genetic diseases, etc.

Thickening: cells don’t get enough nutrients, die off; not enough filtering; causes: scarring (post-thinning/destruction), hyperglycemia

Question 25

Name the epithelium, the tissue, and **4** places where this type of epithelium is found

Answer 25

Stratified squamous This is skin (keratinized) 1. Skin (keratinized) 2. Vagina (nonkeratinized) 3. GI: Esophagus, mouth, anus (nonkeratinized) 4. Urethra (nonkeratinized)

Question 26

Name the epithelium and its function

Answer 26

Transitional Allows for distension (cells flatten when distended), small amount of protection due to more layers of cells, protection from infection due to more layers of cells
