Q

How do endocrine glands secrete hormones?

A

DIRECTLY into bloodstream

17
Q

What type of secretion is water and protein rich?

A

serous (enzymes)

18
Q

What type of secretion is viscous and thick?

A

lubrication or protection

19
Q

Which junction anchors the cell to the basement membrane?

A

hemidesmosomes

20
Q

Where are hormones stored in the thyroid?

A

FOLLICLES

21
Q

What are the functions of epithelium?

A

protection, absorption, secretion, and/or secretion

22
Q

What are the two types of epithelial tissue?

A

covering and lining, glandular

23
Q

What structure is basically long microvilli?

A

stereocilia

24
Q

What is the amorphous protein that is waterproof, resists friction, and relatively impervious to microorganisms?

A

keratin

25
Q

What’s the difference between exocrine and endocrine?

A

exocrine has a secretory duct, endocrine glands secrete the product directly into the blood stream
