Front 24

Describe 5 general characteristics of epithelial tissue

Back 24

1. Polarity

2. Specialized contacts (cells fit closely together forming continuous sheets)

3. Supported by connective tissue

4. Avascular but innervated

5. Regeneration

Front 25

On what basis are epithelial tissues classified

Back 25

number of layers and cell shape

Front 26

List 5 major functions of epithelium in the body, and give examples of each

Back 26

1. protection; skin

2. absorption; stomach lining

3. excretion; sweat

4. secretion; glands

5. filtration; kidney tubules

Front 27

How does the function of stratified epithelia differ from the function of simple epithelia

Back 27

simple = one layer; stratified layer = multiple layers

simple does not offer as much protection

Front 28

Where is ciliated epithelium found

Back 28

lining of the trachea, upper respiratory tract

Front 29

What role does ciliated epithelium play

Back 29

keeps mucos and debris from the lungs by moving in an upward direction

Front 30

Transitional epithelium is actually stratified squamous epithelium with special characteristics.

How does it differ structurally from other stratified squamous epithelia?

Back 30

it is rounded or plump

Front 31

Transitional epithelium is actually stratified squamous epithelium with special characteristics.

How does the structurally difference support its function?

Back 31

The difference in the structure supports the function so that it has the ability to slide over one another so the organ can be stretched.

Front 32

How do the endocrine and exocrine glands differ in structure and function

Back 32

Endocrine glands do not have ducts; their function is to release all hormones into the extracellular fluid where they enter the bloodstream and lymphatic system.

Exocrine glands have ducts; their function is to secrete through the ducts to an epithelial surface

Front 33

tissue:

lining of the esophagus

Back 33

stratified squamous

Front 34

tissue:

lining of the stomach

Back 34

simple columnar

Front 35

tissue:

alveolar sacs of the lungs

Back 35

simple squamous

Front 36

tissue:

tubules of the kidney

Back 36

simple cuboidal

Front 37

tissue:

epidermis of the skin

Back 37

stratified squamous

Front 38

tissue:

lining of the bladder; peculiar cells that have the ability to slide over each other

Back 38

transitional

Front 39

tissue:

forms the thin serous membranes, a single layer of flattened cells

Back 39

simple squamous

Front 40

What are the 3 characteristics of connective tissue

Back 40

1. rich supply of blood vessels

2. composed of many types of cells

3. noncellular, nonliving material (matrix) between the cells

Front 41

What functions are performed by the connective tissue

Back 41

protection, support, and binding

Front 42

How are the functions of connective tissue reflected in its structure

Back 42

the provides strength to protect the body

Front 43

attaches bone to bone and muscles to bones

Back 43

dense fibrous connective tissue

Front 44

insulates against heat loss

Back 44

Front 45

the dermis of the skin

Back 45

Back 49

hyaline cartilage

Front 50

provides a flexible framework for the outer ear

Back 50

elastic cartilage

Front 51

firm, structurally amorphous matrix heavily invaded with fibers; appears glassy and smooth

Back 51

Front 54

walls of large arteries

Back 54

elastic connective tissue

Front 55

Why do adipose cells remind people of a ring wit a single jewel

Back 55

because of he large fat-filled vacuole; nucleus is pushed to the periphery giving the cell a "signet ring" appearance
