What are the three mechanisms of protection of the immune system?

Surface protection, acute inflammation, immune response

1

Surface protection is an example of what kind of immunity?

Innate

2

Acute inflammation is what kind of immunity?

Innate

3

The non-specific process where neutrophils, macrophages, and eosinophils move into an area and complement complex is presented is what mechanism of the immune system?

Acute inflammation

4

What is the mechanism of the immune system primarily used by the epithelium and its cells?

Surface protection

5

What are the two types of adaptive immunity?

Humoral (B cell) immunity and cell mediated immunity

6

Humoral immunity is usually in response to what kind of invasion?

Bacterial

7

What mediates humoral immunity?

B cells and plasma cells with T cell involvement

8

What type of adaptive immunity involves antibody production?

Humoral (B cell) immunity

9

Cell mediated immunity is usually a response to what kind of invasion?

Viruses, fungi, or foreign cells

10

What mediates cell mediated immunity?

T lymphocytes

11

Does cell mediated immunity depend on B lymphocytes?

No

12

Which type of adaptive immunity is a cytotoxic response?

Cell mediated immunity

13

What are the functions of the immune system?

Storage of lymphocytes, increase the numbers of lymphocytes, provide a favorable environment for establishing immunity

14

Humoral immunity and having an incomplete capsule or not one at all are characteristics of what kind of component of the immune system?

Diffuse lymphatics

15

Both humoral and cell-mediated immunities along with the presence of a capsule are characteristics of what component of the immune system?

Lymphoid organs

16

The bone marrow and thymus are examples of which lymphoid organs?

Primary

17

What type of lymphoid organs provides an environment where lymphocytes become immunocompetent?

Primary

18

What kind of lymphoid organ provides an environment where lymphocytes can contact foreign antigens and can interact with each other?

Secondary

19

Large amounts of which antibodies are associated with lymph nodules?

IgG or IgA

20

What is MALT?

Mucosal-Associated Lymphatic Tissue

21

What kind of lymphatics are located within the GI, respiratory, and urogenital tracts?

Diffuse lymphatics

22

The spleen and lymph nodes are examples of what kind of lymphoid organs?

Secondary

23

What occurs in the lymph nodules?

B cells dividing to form B memory cells and plasma cells

24

Secretory IgA is secreted onto what surfaces?

Epithelial

25

Where can we find secretory IgA?

In or on tears, saliva, gut lumen, nasal cavity, and vaginal surface

26

What are the functions of IgA?

Neutralize viruses and bacteria toxins, decrease microbial adhesion to cells

27

What subcategory of MALT is in the GI tract?

GALT (gut-associated lymphatic tissue)

28

Peyer's patches are located where?

Ileum

29

What subcategory of MALT is associated in the respiratory system?

BALT (bronchial-associated lymphatic tissue)
