Question 10

Simple

Answer 10

one layer of cells

Question 11

Pseudostratified

Answer 11

appears to have multiple layers, but does not, fake

Question 12

Stratified

Answer 12

multiple layers of cells

Question 13

Simple squamous

Answer 13

-found in lungs, process of diffusion (molecules move greatly to less concentration),
-found in kidneys (filtration, removing impurities from blood)

Question 14

Simple cuboidal

Answer 14

seen in ovaries and ducts, lumen

Question 15

Simple columnar

Answer 15

-can exist with cilia or without cilia, depending on cell function
-goblet cells
CILIATED (seen in trachea to remove debris, seen in fallopian tubes to ovary; move eggs)
NONCILIATED (seen in stomach & intestines, possesses microvilli for absorption (increasing surface area), includes goblet cells, trachea tissue)

Question 16

Answer 17

a hollow opening

Question 18

Pseudostratified columnar

Answer 18

-all connected to basement membrane
-reaches nuclei in different spots
-possesses cilia which is seen in respiratory tract (bronchideo, trachea, lungs)

Transitional

Answer 19

“shape-shifter”
-cuboidal to squamous
-located in bladder and uterus

Question 20

Stratified squamous

Answer 20

-made of multiple layers
-found in skin, cervix, genital region, oral cavity
-inside skin filled with keratin (protein) (waterproof protects against UV)

Question 21

Stratified cuboidal

Answer 21

-2 or more layers; each cell with a nucleus
-located in ducts of mammary glands, reproductive system of a female, pancreas, sweat glands

Question 22

Stratified columnar

Answer 22

-2 or more layers, 1st attached to basement membrane
-located inside the ducts of glands

Question 23

What is the function and location of epithelial tissue?

Answer 23

function- protection, secretion, absorption, excretion

location- cover body surface, cover and line internal organs, compose glands

Question 24

What is the function and location of connective tissue?

Answer 24

function- bind, support, protect, and fill spaces, store fat, produce blood cells

location- widely distributed throughout the body

Question 25

Answer 26

function- conduct impulses for coordination, regulation, integration, and sensory reception

location- brain, spinal cord, nerves
