Q

Ingestion of foreign body

A

Endocytosis

19
Q

Excretion of undigested foreign bodies

A

Exocytosis

20
Q

Lysosome fuses with phagocyte forming?

A

Phagolysome

21
Q

A large strand-like protein that forms a sponge-like mesh

A

Fibrin

22
Q

This walls off the area and is capable of blocking drainage to lymphatic channels

A

Fibrin

23
Q

This is capable of ingesting and destroying some but not all bacteria

A

Neutrophils

24
Q

This can dissolve neutrophil itself if it dies and liquifies local cells of host and insoluble fibrin wall that was laid down

A

Lysosome

25
Q

Localized or walled off collection of pus

A

Abscess

26
Q

Liquefied material containing dead and dying neutrophils and host cell debris and is eliminated by the body

A

Pus

27
Q

These appear after the neutrophils and respond to chemical liberated by injured cells but more slowly

A

Monocytes

28
Q

These are phagocytic cells but are larger and are capable of ingesting larger particles

A

Monocytes

29
Q

Prime function of these cells is to phagocytize foreign materials, dead cells and debris at the site of inflammation

A

Macrophages

30
Q

Considered the second line of defense

A

Macrophages

31
Q

Considered the first line of defense

A

Neutrophils

32
Q

These cells appear later in the inflammatory process and its prime function is to recognize foreign material and to elaborate an immune system

A

Lymphocytes

33
Q

These cells seek out foreign proteins and inactivates them by binding them into antigen-antibody complexes

A

Lymphocytes

34
Q

Another cell involved in antigen-antibody response, particularly relating to allergy

A

Eosinophil

35
Q

These cells has granules that contain enzymes capable of digesting antigen-antibody complexes

A

Eosinophil

36
Q

These cells begin to appear within the first few days of the inflammatory response

A

Fibroblasts and Angioblast Cells

37
Q

Young connective tissue cells that can produce fibers usually collagen

A

Fibroblasts

38
Q

Endothelial cells (normally line blood vessels) that bud and form fresh capillaries

A

Angioblasts

39
Q

Type of repair wherein replacement of injured area with the same tissue occurs

A

Regeneration

40
Q

Type of repair wherein replacement of injured area with another type of tissue occurs

A

Repair with scarring (Fibrosis)

41
Q

Represents dense bundles of collagen fibers that have been produced from the granulation tissue to replace the injured area

A

Scar

42
Q

Why does a scar appear red?

A

Due to increased capillary supply from granulation tissue

43
Q

Why does a scar appear white?

A

Due to dense bundles of collagen

44
Q

Return of tissue to normal state or state of repair with a scar

A

End of Inflammation
