Question 1

Specific Immunity

Answer 1

Specialized cells (T&B cells) recognize specific foreign molecules called antigens.

Question 2

Nonspecific Immunity

Answer 2

Physical Barriers (skin/mucous membranes), Fever, Inflammation, Specific action by immune cells, enzyme activity to protect against harmful agents.

Question 3

Lymphocytes

Answer 3

White Blood Cell

Question 4

Primary Lymphoid Organs

Answer 4

Red Bone Marrow & Thymus

Question 5

Secondary Lymphoid Organs

Answer 5

LAST

Lymph nodes
Adenoids
Spleen
Tonsils

Question 6

Adenoids

Answer 6

Contain lymphocytes for destruction of invading pathogens

Question 7

Tonsils

Answer 7

Monitor external environment that the mouth/nose are exposed to and react with immune response when appropriate.

Question 8

As lymphocytes mature, they leave the thymus to attack infected cells in lymphatic tissues throughout the body.

Question 9

Spleen

Answer 9

Largest lymph organ
Houses lymphocytes for potential immune response.

Lymph nodes

Answer 10

House lymphocytes and macrophages with destroy foreign material contained in the lymph fluid

Question 11

Lymphatic Vessels

Answer 11

Transport Lymph fluid throughout the lymphatic system.

Question 12

Stem Cells

Answer 12

Differentiate into RBCs, Platelets and immune cells (lymphocytes, neutrophils, macrophages, and white blood cells)
