Q

Endocrine Glands

A
  • ductless
  • released into surrounding interstitial fluid which is picked up by the circulatory system
  • these glands secrete hormones (by exocytosis)
17
Q
  • secretes product into ducts

- secretions are released by body surfaces such as skin, or into body cavities

A

Exocrine Glands

18
Q

Merocrine glands

A

secrete their products by exocytosis

19
Q

Holocrine glands

A

The entire cell ruptures, releasing secretion+dead cell fragments

20
Q

Apocrine glands

A

release contents along with a little bit of cytoplasm

21
Q

What cavities do epithelial tissue cover?

A

urogenital, digestive, and respiratory

22
Q

What else does epithelial tissue cover?

A

the walls and organs of the closed ventral body cavities

23
Q

An upper free surface exposed to the body exterior

A

Apical

24
Q

Fingerlike extensions of the plasma membrane

A

Microvilli

25
Q

Is epithelial tissue innervated?

A

Yes

26

A 
Apical surface
Epithelium
Basal lamina
Reticular lamina

27
Q

What are the unicellular exocrine glands?

A
