Question 1

epithelial tissue functions (5)

Answer 1

1) Protecting underlying structures
2) Acting as a barrier
3) Permitting the passage of substances
4) Secreting substances
5) Absorbing substances

Question 2

epithelial tissue characteristics (4)

Answer 2

1) Mostly composed of cells
2) Has an exposed surface
3) Covers body surfaces
4) Attaches at the basal surface

Question 3

tight junctions

Answer 3

cell connection structures that form form barriers and anchor cells to each other

Question 4

One layer of flat cells function

Answer 4

Where diffusion and filtration are common. To protect against friction

Question 5

One layer of cubelike cells function

Answer 5

Greater secretory capabilities

Question 6

One layer of tall, columnar cells function

Answer 6

Providing a thicker barrier for more absorption, secretion, and protection

Question 7

gap junction

Answer 7

cell connection structures that allow for cellular communication

Question 8

goblet cell

Answer 8

Mucus-producing epithelial cell that has its apical end distended with mucin.

Question 9

merocrine

Answer 9

most common form of secretion through exocytosis, which releases secretory products

Question 10

apocrine

Answer 10

a portion of the epithelial cell pinches off releasing cytoplasmic contents

Question 11

halocrine

Answer 11

The release of secretory products through the shedding of entire cells
