A protein molecule produced by B cells.

Antibody

1

A substance that can cause a specific immune response and then reacts with the products of the response.

Antigen

2

Nodes around the axilary (armpit) area that receive lymph drainage from the upper arm and the scapular and pectoral regions; they drain into the subclavian trunk.

Axilary lymph nodes

3

A type of lymphocyte that specializes in producing antibodies.

B cell

4

A sac on the inferior portion of the thoracic duct that holds chyle, a milky yellow fluid that drains from the intestines.

Cisterns chyli

5

An immune defense system of plasma proteins that destroy microbes.

Complement system

6

A protein released by cells that affects cell-to-cell communication and interactions.

Cytokines

7

One of several types of antibodies; a protein derived from blood that has been infected with a pathogen; antibodies are created, isolated, and injected into the human body to cause short-term immunity.

Gamma globulin

8

One of several small nodes deep to the tensor fascia lata that receive lymph drainage from the deep structures of the lower limbs.

Inguinal lymph node

9

A natural cytokine secreted by the body to keep viruses from infecting cells and replicating.

Interferon

10

One of the lymphatic vessels that transports a milky fluid (chyle) through the small intestine and the mesenteric glands to the thoracic ducts.

Lacteal

11

One of a chain of lymph nodes located around the inferior vena cava.

Lumbar lymph node

12

The beginning of a lymphatic vessel.

Lymph capillary

13

A tube that allows the passage of lymph from one place to another.

Lymph duct

14

A bean-sized organ located throughout the body.

Lymph node

15

A facial lymph node that is located at the point where the facial artery crosses the mandible.

Mandibular lymph node

16

A cell that that remains after the body mounts an immune response to an antigen and is capable of an immediate response to the reappearance of the same antigens.

Memory cells

17

A node located in and around the abdominal membranes.

Mesenteric lymph nodes

18

A large, oval-shaped mass of lymphatic tissue located in the wall of the pharynx at the back of the throat; the structure commonly referred to as the tonsils.

Palatine tonsils

19

Cell capable of "swallowing up" other cells (harmful ones) and even digesting them.

Phagocyte

20

A group of small lymphatic nodules located on the back and roof of the nasopharynx.

Pharyngeal tonsils

21

Two groups of nodes located around the back of the knee that drain the skin of the posterior leg; deep structures of the leg, and side of the foot.

Popliteal lymph nodes

22

A type of cell derived from the thymus that helps coordinate immune system functions through the secretion of hormones.

T cell

23

Specialized T cells that destroy infected or other diseased cells, including cancer cells; the most significant component of the cellular immune response.

T-cytotoxic cells

24

A type of T cell that regulates the immune response.

T-helper cell

25

The major efferent lymph duct into which most lymph nodes drain.

Thoracic duct

26

Lymphatic tissues covered by a membrane and located on either side of the throat.

Tonsils

27

A localized collection of pus caused by an infection

Abscess

28

The most common type of childhood leukemia; a rapid growing cancer of the blood causing an abnormal increase in white blood cells.

Acute lymphoblastic leukemia

29

A type of cancer in the blood that usually affects adults; it affects the immature blood cells in the bone marrow.

Acute myeloblastic leukemia
