veriform apendix

19
Q

What does MALT stand for

A

mucus-associated lymphatic tissue

20
Q

What does GALT stand for and what is it associated with

A

gut-associated lymphatic tissue; associated with alimentary tract

21
Q

What does BALT stand for and what is it associated with

A

bronchus-assocaited lymphatic tissue; associated with the respiratory system

22
Q

This is a capsulated organ along the pathway of lymphatic vessels

A

lymph node

23
Q

What is the function of a lymph node

A

filtering system

24
Q

What are the parts of a lymph node

A 
capsule
trabeculae
reticular tissue
hillum
cortex
medulla
25
Q

This is the dense connective tissue portion of a lymph node

A

trabeculae

26
Q

This is the meshwork like portion of mesenchymal cells of a lymph nodes

A

reticular tissue

27
Q

What are the portions of the cortex of the lymph node

A 
superficial (nodular) cortex
deep cortex (paracortex)
28
Q

What are the portions of the superficial cortex of the lymph node

A 
lymphatic nodules (primary and secondary)
germinal centers
29
Q

What are the portions of the medulla of the lymph node

A

medullary cords

medullary sinuses

30
Q

What are the cells in the reticular meshwork

A

reticular cells
dendritic cells
marcophages
follicular dendritic cells

31
Q

What is the flow of lymph through the lymph node

A 
afferent lymph vessel
subcapsular (cortical) sinus
trabecular sinus
medullary sinus
efferent lymph vessel
32
Q

This organ is the site of thymic cell education; in which T cells mature and differentiate into immunocompetent T cels

A

thymus

33
Q

This organ filters and monitors the blood immunological just as the lymph nodes monitor lymph

A

spleen

34
Q

What two pulps does the spleen consist of

A

red and white pulp

35
Q

This pulp of the spleen consists of blood filled venous sinuses surrounded by cords of splenic tissue called splenic cords

A

red pulp

36
Q

What is the function of the red pulp

A

blood filtration

37
Q

This pulp of the spleen consist of mostly lymphocytes aggregating around branches of the splenic artery creating a periarterial lymphatic sheath

A

white pulp

38
Q

What is the function of white pulp

A

carry out immune functions similar to lymph nodes
