Question 14

What organs have transitional tissue?

Answer 14

Ureter

Question 15

Glandular Epithelia

Answer 15

one or more cells that makes and secrets an aqueous fluid called a secretion

Question 16

Endocrine Glands

Answer 16

• ductless
• released into surrounding interstitial fluid which is picked up by the circulatory system
• these glands secrete hormones (by exocytosis)

Question 17

• secretes product into ducts

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

Answer 17

Exocrine Glands

Question 18

Merocrine glands

Answer 18

secrete their products by exocytosis

Question 19

Holocrine glands

Answer 19

The entire cell ruptures, releasing secretion+dead cell fragments

Question 20

Answer 20

release contents along with a little bit of cytoplasm
