Q

are oval or bean-shaped secondary lymphoid organs arrayed along lymphatic vessels

A

Lymph nodes

25
Q

What are the main purpose of lymph nodes?

A

Removes antigens and are sites of activation for B and T cells

26
Q

carry antigen-containing lymph from the tissues into the node

A

Afferent lymphatic vessels

27
Q

carry lymph away form a lymph node

A

Efferent lymphatic vessels

28
Q

Lymph nodes are covered by a ___ tissue capsule

A

Dense connective

29
Q

bundles of collagen fibers that separate lymph nodes into sections

A

Trabeculae

30
Q

found beneath the capsule, where the afferent lymphatic vessels empty into

A

Subcapsular sinus

31
Q

area just below the subcapsular sinus

A

Outer cortex

32
Q

lighter staining central areas in the follicles, formed by B cells proliferating in response to antigen

A

germinal centers

33
Q

lymphocytes exit blood vessels and enter here

A

Deep cortex

34
Q

shaped into elongated masses of cells called medullary cords

A

Central medulla

35
Q

contain both types of lymphocytes as well as macrophages and plasma cells, which are derived from B cells

A

Medullary cords

36
Q

a shallow indentation where efferent lymphatic vessel and blood vessels are found

A

Hilum

37
Q

fist-sized,blood rich organ located to the left of, and dorsal to the stomach. It performs the same cleansing function for the blood as the lymph nodes do for the lymph

A

Spleen

38
Q

Stores platelets and breakdown product of erythrocytes and allows intimate contact between blood and lymphocytes

A

Spleen

39
Q

filtering and processing of red blood cells and pathogens occur

A

Red pulp

40
Q

surround the central arteries, it is made up of collections of lymphocytes

A

White pulp

41
Q

Blood trickles through the spaces within these cords and squeezes into the ___, this returning to the venous circulation

A

venous sinusoids

42
Q

recognize and remove aged erythrocytes and platelets

A

Macrophages

43
Q

True or False. In stained splenic tissue, the red pulp looks darker than the white pulp because of the many darkly staining nuclei of densely packed lymphocytes

A

False. White is darker then red pulp

44
Q

the red pulp is primarily responsible for removing old ___

A

Erythrocytes

45
Q

the white pulp is the site of ___ between antigen and lymphocytes

A

immune interactions

46
Q

What does MALT stand for?

A

mucosa-associated lymphoid tissues

47
Q

found at the posterior end of the oral cavity, they trap microorganisms that enter the body through the oral or nasal cavities

A

Tonsils

48
Q

is embedded in the wall of the nasopharynx

A

Pharyngeal tonsil or adenoids

49
Q

a collection of lymphoid nodules at the base of the tongue

A

lingual tonsil

50
Q

True or False. Tonsils can become overwhelmed by bacteria, becoming sites that harbor, rather than kill the organisms

A

True

51
Q

a blind sac stemming from the wall of the first part of the large intestine. Its walls contain a large concentration of lymphoid follicles

A

Appendix

52
Q

True or False. If the mouth of the appendix becomes plugged, the pressure inside falls

A

False. The pressure rises

53
Q

found in the mucosa of the distal portion of the small intestine

A

Peyer’s patches

54
Q

site for differentiation of lymphocytes into mature T cells

A

Thymus

55
Q

Where is the thymus located?

A

Mediastinum

56
Q

as we age, the thymus decreases in size and activity as the thymus tissue is gradually replaced by fat and connective tissue.

A

Thymic atrophy

57
Q

Thymic lobes are divided into

A

lobules

58
Q

clusters of keratinized epithelial cells with a whorled appearance that are scattered throughout the medullary area

A

Thymic corpuscles
