Chp 14- Cells of Immune SYstem

Question 1

Leukocytes (WBCs) divided into 2 categories

Answer 1

Granulocytes (granules present) and Agranulocytes (no granules)

Question 2

Granulocytes Cell Types (The phils)

Answer 2

Neutrophils, Basophils, Eosinophils

Question 3

activated in initial stages of infection; accumulates at site of injury; quickly phagocytizes bacteria

Answer 3

Neutrophils

Question 4

granulocyte that releases histamine, involved in inflammation and allergic responses

Answer 4

Basophil (in tissue, these are mast cells)

Question 5

important in ridding body of parasitic worms; produce toxic proteins against multicellular parasites

Answer 5

eosinophils

Question 6

Agranulocyte Cell Types

Answer 6

Monocyte, Lymphocyte, Dendritic Cells

Question 7

agranulocyte that is not active while in blood, but enter into body tissue to mature into macrophages & dendritic cells

Answer 7

monocytes

Question 8

Monocytes become

Answer 8

macrophages (big eaters/ phagocytic)

Question 9

phagocytic cell that resides in tissues and removes microbes & damaged cells

Answer 9

Macrophages “big eaters”

Question 10

Agranulocyte; group of leukocytes involved in adaptive immunity

Answer 10

Lymphocytes

Question 11

3 Main Lymphocytes

Answer 11

T-cells (80%). B-cells (15%), NK cells (5%)

Question 12

lymphocyte cells that make antibodies; turns into plasma cells & produces antibodies; involved in adaptive immunity

Answer 12

B cells

Question 13

lymphocyte cells that mature in thymus; involved in adaptive immunity

Answer 13

T cells

Question 14

lymphocyte cells that has ability to kill multiple types of cells; releases perforins that perforate membrane; involved in innate immunity

Answer 14

NK cells

Question 15

Blood consists of 2 parts , ____

Answer 15

formed elements (cell component) and plasma (fluid component)

Question 16

Three categories of blood cells

Answer 16

Red blood cells (erythrocytes), White Blood cells (Leukocytes), Platelets

Question 17

Red blood cells & carry O2 in the blood

Answer 17

Erythrocytes

Question 18

These cells are important to ALL host defenses

Answer 18

White Blood Cells (Leukocytes)

Question 19

The formation and development of blood cells that originates from hemopoietic stem cells, found in bone marrow & induced by CSFs

Answer 19

hematopoiesis

Question 20

Proteins that function as chemical messengers, allows cells to communicate

Answer 20

cytokines

Question 21

group of cytokines that direct the development of various types of blood cells from hematopoietic stem cells

Answer 21

Colony Stimulating factors (CSFs)

Question 22

Cytokines that induce cells to resist viral replication; they also help regulate the immune response

Answer 22

interferons

Question 23

antigen presenting cells that engulf material & bring it to the cells of the adaptive I.S; initiate adaptive immune system; found in tissues

Answer 23

Dendritic cells

Question 24

Programmed death of “self” cells that does not cause inflammation.

Answer 24

apoptosis

Question 25

Membrane-bound vacuole that contains the material engulfed by a phagocyte.

Answer 25

phagosome

Question 26

cells that engulf and digest microbes

Answer 26

phagocyte

Question 27

Membrane-bound vacuole generated when a phagosome fuses with lysosomes

Answer 27

phagolysosome

Question 28

arms of a phagocyte/protozoa that enclose extracellular material

Answer 28

pseudopods
