Flashcards in 1-5 Cells & Tissues of the Immune Response Deck (16):
1

Name the primary and secondary immune organs

Primary:
Thymus
Bone marrow

Secondary:
lymph nodes, spleen

2

What is the name of the cell type:
Lymphocytes produced in the thymus that place an active role in cell-mediated immunity

T Cells

3

What is the name of the cell type:
Lymphocytes produced in the bone marrow that are heavily involved in humoral immunity

B cells

4

What is the name of the cell type:
large cells that play a role in innate immunity by phagocytizing unhealthy and non-self cells

Macrophage

5

What is the name of the cell type:
Leukocytes that travel to sites of infection in response to inflammation and differentiate into macrophages and dendritic cells

Monocytes

6

What is the name of the cell type:
One of the first cells in circulation to interact with bacteria. Kills by phagocytosis.

Also known as polymorphonuclear lymphocytes (PMNs)

Neutrophils

7

What is the name of the cell type:
kills antibody-coated parasites through release of granule contents

Eosinophils

8

What is the name of the cell type:
Regulate immune response to parasites

Basophils

9

What is the name of the cell type:
Expel parasites through release of histamine and other active chemicals

Mast cells

10

In which ways are these immune cell types identified or described?

Morphological criteria: stains acidic or basic, then morphology is noted (cell shape, size, nuclear shape)

Antigenic Criteria: Identifies cells based on antibody recognition of antigens present on their surface....the cluster of differentiation (CD) is used to organize the antigens

11

Which type of immunity (innate/adaptive) is characterized by a rapid response, a fixed response, has limited number of specificities, and is constant during response?

Innate immunity

12

Which type of immunity (innate/adaptive) is characterized by a slower variable response (days to weeks), highly selective specificities, and improves during response?

Adaptive immunity

13

What is meant by the word opsonize and what are two examples of opsonins?

An opsonin is an antibody or other substance that binds to foreign microorganisms or cells, making them more susceptible to phagocytosis

Examples: Complements or antibodies

14

Which cell type is the most abundant leukocyte (white blood cell)?

Neutrophils (polymorphonuclear leukocytes)

about 60-70% of all circulating WBCs

15

which cell type differentiates into macrophages upon entering into tissues and become better effector cells?

Monocytes

16

which cell types produces antibodies?

B- Cells
