Immune System

Question 1

Immune System

Answer 1

the body’s final line of defense against invading microorganisms, harmful chemicals, and foreign bodies

Question 2

the body’s final line of defense against invading microorganisms, harmful chemicals, and foreign bodies

Answer 2

Immune System

Question 3

Two Kinds of Immune Cells:

Answer 3

B-cells and T-cells

Question 4

B-cells and T-cells

Answer 4

Two Kinds of Immune Cells:

Question 5

Four Types of Cells that Protect the Body from Infection

Answer 5

neutrophils, lymphocytes, monocytes, eosinophils

Question 6

Four Types of Cells that Protect the Body from Infection

Answer 6

neutrophils, lymphocytes, monocytes, eosinophils

Question 7

Neutrophils

Answer 7

body’s main defense against infection and antigens. High levels may indicate an active infection; a low count may indicate a compromised immune system or depressed bone marrow (low neutrophil production)

Question 8

body’s main defense against infection and antigens. High levels may indicate an active infection; a low count may indicate a compromised immune system or depressed bone marrow (low neutrophil production)

Answer 8

Neutrophils

Question 9

Lymphocytes

Answer 9

protection of the body from viral infections such as measles, rubella, chicken pox, or infectious mononucleosis. Elevated levels may indicate an active viral infection and a depressed level may indicate an exhausted immune system; or, if the neutrophils are also elevated, an active infection

Question 10

protection of the body from viral infections such as measles, rubella, chicken pox, or infectious mononucleosis. Elevated levels may indicate an active viral infection and a depressed level may indicate an exhausted immune system; or, if the neutrophils are also elevated, an active infection

Answer 10

Lymphocytes

Question 11

Monocytes

Answer 11

fight severe infections and are considered the body’s second line of defense against infection. Elevated levels are seen in tissue breakdown, chronic infections, carcinomas, leukemia (monocytic), or lymphomas. Low levels indicate a good state of health

Question 12

fight severe infections and are considered the body’s second line of defense against infection. Elevated levels are seen in tissue breakdown, chronic infections, carcinomas, leukemia (monocytic), or lymphomas. Low levels indicate a good state of health

Answer 12

Monocytes

Question 13

Antibodies

Answer 13

immune system-related proteins called immunoglobulins. Some antibodies destroy antigens directly; others indirectly by making it easier for white blood cells to destroy the antigen

Question 14

immune system-related proteins called immunoglobulins. Some antibodies destroy antigens directly; others indirectly by making it easier for white blood cells to destroy the antigen

Answer 14

Antibodies
