100

Contains lymphocytes and macrophages that clean lymph; comprise tonsils and appendix
What is lymphatic nodules

100

where B cells are located
What is lymphatic nodules/ follicles

100

site of differentiation of T cells
What is thymus

100

repeated exposure of the skin to certain chemicals, eventually the foreign substance activates T cells, the T cells and macrophages release chemical factors, which cause eruptions and inflammation of the skin
What is delayed reaction allergy

100

Lymphatic vessels have walls similar to those of ________.
What are veins?

200

filter harmful particles from lymph before returning it to the blood and monitor body fluids; small and bean-shaped
What is lymph nodes

200

site of differentiation of B cells
What is red bone marrow

200

where do T cells originate
What is red bone marrow

200

an inherited ability to overproduce IgE, commonly called an allergy
What is immediate reaction allergy

200

The aggregations of lymph nodules found within the mucosal lining of the small intestines are called ________________.
What is Peyer's patch?

300

major locations of lymph nodes; give one region and one cavity
What is cervical, axillary, supratrochlear, and inguinal regions; pelvic, abdominal, and thoracic cavities

300

B cells differentiate into what?
What is plasma cells or memory B cells

300

How do T cells attack foreign, antigen bearing cells
What is direct cell-to-cell contact; cell-mediated immunity

300

An antigen that triggers allergic responses
What is allergen

300

Where does the right lymphatic duct receive its lymph from?
What is the right thorax?

400

bilobed gland in the mediastinum; houses lymphocytes and secretes hormones called thymosins
What is thymus

400

List one purpose of B cells
What is to attack pathogens and differentiate into plasma cells that secrete antibodies

400

four types of specialized T cells
What is helper T cell, Supressor T cell, Killer T cell, and Memory T Cell

400

What happens in an initial exposure to an allergen?
What is IgE attaches to the cell membranes of widely distributed mast cells and basophils

400

Where does the left lymphatic duct receive its lymph from?
What is the cisterna chlyi in the abdomen?

500

largest lymphatic organ, contains white pulp and red pulp tissue; houses macrophages that remove foreign particles and cell debris
What is spleen

500

How does a B cell become activated?
What is its antigen receptor encounters its matching antigen, but most B cells need helper T cells for activation

500

functions of four types of specialized T cells (list two)
What is Suppressor: stop the work of helper T cells when not needed; Helper: signals others to be produce antibodies; Memory: provide for future immune protection; Killer: recognizes and combines with nonself antigens to release perforin that destroys cells

500

give the purpose of allergy mediators and a few examples
What is dilate arterioles and increase vascular permeability; histamine and leukotrienes

500

Where do you find lymph nodes?
What is groups or chains along the paths of the larger lymphatic vessels throughout the body?
