LINES things exposed to the outside world/open to exterior. PROTECT stomach from acids, protect lungs from harmful air, PRODUCE mucous to reduce friction

Can be found in the respiratory system, digestive system, urinary system, reproductive system

35
Q

Uses ciliated pseudostratified epithelium to produce mucous and keep things moving in the digestive tract so nothing gets stuck

36
Q

A

Found around organs and functions to protect organs and hold them in place

37
Q

What is a parietal layer?

The outside layer of the Serous membrane that lines the organ cavity space

38
Q

What is the visceral layer?

A

The internal layer of the Serous membrane That covers the internal organs

39
Q

What is Serous fluid (Transudate)

A

The fluid between the visceral and parietal layer of the Serous membrane that works to reduce friction

40
Q

What is every macro membrane composed of?

A

At least two primary tissue types.
And epithelial part bound to connective tissue.

41

Where is the endothelium located?

A

Lining blood vessels and the heart

43
Q

Where is the endothelium located?

A

Lining blood vessels and the heart

44
Q

What are the two ways tissues can repair?

A

Regeneration and fibrosis

45
Q

What are the two types of tissue repair?

A

Regeneration and fibrosis

46
Q

What are the two types of tissue repair?

A

Regeneration and fibrosis

47
Q

Describe how tissue gets repaired by generation

A

Destroyed tissue gets replaced with the same tissue. Original function is restored.

48
Q

Describe how tissues get repaired by fibrosis

A

Connective tissue replaces the destroy tissue. Original function is lost.

49
Q

What are the two main types of epithelial tissue and what are their functions?

A

Covering and lining epithelia- covers external and internal surfaces

Gladular epithelia- secretory tissue in glands

50
Q

How does epithelial tissue get its nutrients?

A

Epithelial tissue is a vascular so it doesn’t get direct blood supply, oxygen and nutrients diffuse up into the epithelial tissue from underlying connective tissue

51
Q

What is the apical surface?

A

The upper surface up epithelial tissue.
It’s exposed to the environment or internal body cavity (lumen)

52
Q

What is the lumen?

A

Inside space of a tube structure or organ

53
Q

Describe what the basal surface is

A

A thin layer of collagen and adhesive proteins that sit on the basement membrane and anchors epithelial tissue to the underlying connective tissue.

54
Q

Describe characteristics of simple squamous epithelium

A

Flat thin cells, whose function is absorption and secretion, and can be found in blood vessels and the alveoli (tiny air sacs in lungs)

55
Q

Describe function of simple cuboidal epithelium and where they can be found

A

Cube like cells, who function is absorption and secretion, and could be found in glands like the thyroid and kidney tubules.

56
Q

Describe simple columnar epithelium

A

Tall Column shaped cells with goblets. Functions are absorption and secretion of mucous

57
Q

Are simple epithelium lining epithelium or gladular epithelium?

A

Gladular.
Due to only having one layer, nutrients and other stuff can be absorbed and secreated in and out of the cell

58
Q

Describe the function of pseudostratified columnar epithelial and where it could be found.

A

Appear stacked, but only has one layer. Has goblet cells and cilia. Function is protection by secreting mucus so things don’t get stuck in upper respiratory tract. Found in the trachea and bronchioles but not in the lungs

59
Q

What is the function of stratified epithelia?

A

This is your skin and the function is to protect

60
Q

Name the three kinds of stratified epithelia

A

Keratinized epithelium, non-keratinized epithelium transitional epithelium

61
Q

What is the function of keratin?

A

A waterproofing protein that stops water from coming in or leaving. It’s found in fingernails and hair.

62
Q

Describe keratinized stratified squamous epithelium

A

Multi layered. SURFACE HAS DEAD SQUAMOUS CELLS packed with keratin found an epidermis of SKIN. protects against microorganisms decreases water movement due to keratin.

63
Q

Describe non-care denies stratified squamous epithelium

A

Multi layered. NO DEAD CELL LAYER. Protection, abrasion resistant, moist, slippery layer. Found in the tongue, mouth, esophagus, vagina.

64
