Flashcards in 2.6 Lymphoid Tissue Deck (24):
1

A milky fluid containing emulsified fat and other products of digestion formed in the small intestine

Chyle

2

Drains the right side of the neck, thorax and upper limbs

Right lymphatic duct

3

Drains the lower half of the body

Thoracic duct

4

A dilated sac in the inferior end of the thoracic duct; it is where the main lymphatic vessels of the abdomen and intestines converge

Cisterna chyli

5

Where the right lymphatic duct and throacic duct will converge and drain into

Subclavian veins

6

Localized type of edema which occurs when lymph does not drain from an area of the body

Lymphedema

7

Most abundant and only antibody that crosses the placental barrier and provides immunity for the newborn for the first 6 months

IgG

8

First antibodies produced in an initial immune response; activates complement

IgM

9

Antibody in secretions including milk

IgA

10

Antibody present in the surface of B lymphocytes

IgD

11

Antibody present in allergic reactions and parasitic infections

IgE

12

Antigen-antibody reaction where the antibody blocks the adhesion of the antigen to cells and inactivates toxins

Neutralization

13

Antigen-antibody reaction where where the antibody cross links cell, forming clumps, reducing free antigen, to be ingested by phagocytes

Agglutination

14

Antigen-antibody reaction where the antibody corss links circulating particles forming insoluble antigen-antibody complex

Precipitation

15

Primary lymphoid organs

ThymusBone Marrow

16

Secondary lymphoid organs

TonsilsLymph nodesspleenMALT

17

Embryonic origin of the thymus

MesodernEndoderm

18

Component of lymphoid organs where arteries enter and where veins and efferent lymphatic vessels leave

Hilum

19

Main function of spleen

Destruction of aged erythrocytes

20

Location of Peyer's patch

Ileum

21

Dome-shpaed cells in the covering of peyer's pathces that capture antigens for presentation to T lymphocytes

M cells

22

Lined with low cuboidal epithelium that has microfolds instead of micovilli

GALT

23

Location of BALT

walls of bronchi

24

Collectively called Waldeyer's ring

Tonsils made up of palatine, pharyngeal, and lingual tonsils
