Chapter 14 - Lymphatic System Flashcards

1
Q

What is adaptive immunity?

A

The ability to recognize and remember specific antigens and mount an attack on them.

Humoral (B cells) and cell-mediated mediated immunity (T cells) are examples .

Q

What is antigen?

A

Substance that the body recognizes as foreign; evokes an immune response.

Most antigens are proteins or proteins fragments found on the surface of bacteria, viruses, or organ transplant, tissue cells.

Q

What is a B cell (B lymphocyte)?

A

Lymphocyte that matures into a plasma cell to secrete antibodies.

The B refers to the bone marrow, which is where B cells, most often originate.

Q

What is cell-mediated immunity?

A

T cell (cytotoxic, helper, and suppressor) respond to antigens and destroy them; a type of adaptive immunity.

16
Q

What is humoral immunity?

A

B cells produce antibodies after exposure to specific antigens; type of adaptive immunity

17
Q

What is immunity?

A

Body’s ability to resist foreign organisms and toxins, that damage, tissues and organs.

18
Q

What are the types of the immunity?

A

Adaptive and natural

19
Q

What are immunoglobulins?

A

Antibodies , secreted by plasma cells (mature B cells) in response to the presence of an antigen.

20
Q

What are the examples of immunoglobulins?

A

IgA,
IgE,
IgG
IgM
IgD

21
Q

What is immunotherapy?

A

Use of immune cells, antibodies, or vaccines to treat disease

22
Q

What are inguinal nodes?

A

Lymph nodes in the groin region

23
Q

What are interferons?

A

ProteinS (cytokines) secreted by T cells and other cells to aid and regulate the immune response

24
Q

What are interleukins?

A

Proteins (cytokines) that stimulate the growth of B and T lymphocytes

25
Q

What is interstitial fluid?

A

Fluid in the spaces between cells.

This fluid becomes lymph when it enters lymph capillaries.

26
Q

What is lymph?

A

Thin, watery fluid found within lymphatic vessels, and collected from tissues throughout the body

27
Q

What are lymph capillaries?

A

Tiniest, lymphatic vessels

28
Q

What are lymphoid organs?

A

Lymph nodes.
Spleen.
Thymus gland.
Tonsils
Adenoids

29
Q

What is lymph node?

A

Collection of stationary, solid, lymphatic, tissue along lymph vessels; contains cells (lymphocytes, and macrophages) that fight infection

30
Q

What is a lymph vessel?

A

Carrier of lymph throughout the body; lymphatic vessels empty lymph into veins in the upper part of the chest

31
Q

What is a macrophage?

A

Large phagocyte found in the lymph nodes, and other tissues of the body.

32
Q

Phag/o

A

Eat, or swallow

33
Q

What are mediastinal nodes?

A

Lymph nodes in the area between the lungs in the chest cavity

34
Q

What are mesenteric nodes?

A

Lymph nodes in the mesentery (intestinal region)

35
Q

What is monoclonal antibody?

A

Antibody produced in a laboratory to attack antigens and to destroy cells; useful in immunotherapy

36
Q

What is natural immunity?

A

Protection that an individual is born with to fight infection, such as
Neutrophils.
Monocytes.
Macrophages.
NK cells.

It is not antigen specific, and does not elicit memory.

37
Q

What are paraaortic nodes?

A

Lymph nodes near the aorta in the lumber (waist) area of the body
