Question 8

Lymph nodes

Answer 8

Located in clusters along the pathway of lymphatic vessels

• small as a pinhead or Lima bean
• performs filtration of lymph on its way to the blood

Question 9

Afferent lymphatic vessels

Answer 9

Deliver lymph to the node (to carry toward)

Question 10

Efferent lymphatic vessels

Answer 10

Carey lymphatic fluid away from lymph node (carry away from)

Question 11

Thymus

Answer 11

Endocrine gland located in the mediastinum

Question 12

T lymphocytes or T cells

Answer 12

Produce cell mediated immunity

Question 13

-

Question 15

Pharyngeal tonsils

Answer 15

Aka adenoids when the become swollen

Question 16

Answer 19

Shock resulting from severe allergic reaction

Could be fatal

Question 20

Nonspecific immunity aka innate immunity

Answer 20

Maintained by mechanisms that attack any abnormal substance that threatens internal environment
-aka general protection rather than Protection from one specific threat

Question 21

Inflammatory response

Answer 21

Nonspecific immune process produced in response to injury & resulting in redness, pain, heat, swelling & causing movement of wbc to the affected area

Question 22

Specific immunity aka adaptive immunity

Answer 22

Includes protective mechanisms that cover very specific protection against certain types of threatening microorganisms or other toxic materials
-involves memory and the ability to recognize & respond to harmful bacteria

Question 23

Immunization

Answer 23

Artificial exposure to disease to produce acquired immunity

Question 24

Antibodies

Answer 24

Protien compound that destroys specific substances

Question 25

Combining sites

Answer 25

Antigen binding site. | Shape of each combing site is complementary to the shape of a specific antigen

Question 26

Humoral aka antibody mediated immunity

Answer 26

Immunity that is produced when antibodies make antigens unable to harm the body

Question 27

Agglutinate

Answer 27

Stick together in clumps

Question 28

Complement cascade

Answer 28

Chemical reactions involving proteins. - triggered by certain antibody antigen reactions - results in the formation of tiny protein rings that create holes in a foreign cell & thus cause it's destruction

Question 34

B cells aka B lymphocyte

Answer 34

Lymphocyte Activated B cells develop into plasma cells Then secretes antibodies into blood

Question 35

Plasma cells aka effector cells

Answer 35

Type of b lymphocyte | White blood cells that secretes huge amounts of antibody into the blood

Question 36

Memory cell

Answer 36

Cell that remains in reserve in the lymph nodes until its ability to secrete antibodies is needed

Question 37

Answer 37

Small proteins produced by the immune system that inhibit virus multiplication
