1

Lymphocytes and Macrophages

Immune Cells

2

Will attack if doesn't recognize (foreign objects).

Antigens

3

Made in bone marrow then travel to thymus. Recognize small cancer (antigens) cells and destroy them.

T Lymphocytes

4

Destroy the target cell by binding to antigen and releasing enzymes and chemicals which destroys cell.

Killer T Cells

5

Remains in lymph nodes for years ready to activate response if invading cell returns.

Memory T Cells

6

T Cells attack foreign objects such as tumor cells and virus cells.

Natural Killer Cells

7

Produced in bone marrow then moved to spleen and lymphoid tissue. After exposure to antigen they become anti-body producing cells.

B Lymphoctyes

8

First exposure to antigen, antibodies or T cells are developed, and takes several days to weeks.

Primary response

9

Repeat exposure occurs. Memory cells stimulate production of large numbers of matching anti-bodies or T cells quickly.

Secondary response

10

Immunity is acquired ____ & ____?

Actively and passively

11

Antibodies developed after direct exposure to antigen.

Active natural immunity

12

Antibodies stimulated by a vaccine.

Active artificial immunity

13

Antibodies transferred from breastmilk or across placenta.

Passive natural immunity

14

Injection of antibodies from person or animal into a second person. Example: Rabies

Passive artificial immunity

15

Identical Twins

Isograft

16

Body's reaction immediately during or after transplant?

Hyperacute rejection

17

Body's reaction several weeks later to transplant?

Acute rejection

18

Body's reaction months to years later to transplant?

Chronic rejection

19

Decreases immune response to prevent rejection.

Immunosuppressant therapy

20

Is a common environmental antigen which stimulates an inappropriate immune response.

Allergen

21

Occurs in nasal mucosal. Sneezing, watery nose/eyes, itching, and typically seasonal.

Hay Fever

22

Chronic with genetic component, typically occurs on face, trunk, and extremities.

Eczema

23

Allergic reaction to bronchial mucosa.

Asthma

24

Life-threatening systemic reaction. Decreased blood pressure, airway obstruction, and severe hypoxia.

Anaphylactic shock

25

Block response of tissues to histamine.

Antihistamine (Benadryl)

26

Decreased immune response and stabilized vascular system.

Glucocorticoids

27

Primarily affects females 20 to 40 years old. Chronic inflammatory disease.

SLE. Systemic Lupus Erythematosus

28

Butterfly rash, joint inflammation, pleurisy, and carditis.

Signs and symptoms of SLE

29

How many pairs of chromosomes?

22

30

How many pairs of sex chromosomes?

1
