Question 1

Which factor is part of specific immunity?
A) Complementary proteins
B) Mucous membrane
C) Lymphocytes
D) Inflammation

Accepted Answer

Specific defense mechanisms are selective and directed against particular pathogens, provide immunity, and involve lymphocytes. Types of lymphocytes include B cells, which mature in bone marrow, and T cells, which mature in the thymus.

Question 2

Which structure is attached to the cecum of the large intestine?
A) Tonsil
B) Thymus
C) Peyer patch
D) Vermiform appendix

Accepted Answer

The vermiform appendix is attached to the cecum which is the first region of the large intestine. Lymphatic tissue is found inside the appendix.

Question 3

What does the S in the acronym SHARP stands for?
A) Spleen
B) Sensory
C) Swelling
D) Subjective

Accepted Answer

The S in SHARP stands for swelling.

Question 4

Which condition is characterized by prolonged, severe, and disabling tiredness that is unrelieved by rest and may worsen with activity?
A) Allergy
B) Chronic fatigue syndrome
C) Systemic lupus erythematosus
D) Acquired immunodeficiency syndrome

Accepted Answer

Chronic fatigue syndrome (CFS), also called immune dysfunction syndrome, is characterized by prolonged and severe tiredness and disabling fatigue. This feeling is not relieved by rest and may worsen with physical or mental activity.

Question 5

Which term refers to defense mechanisms that are directed against all pathogens and foreign agents and include barriers, cellular responses, and inflammation?
A) Specific
B) Artificial
C) Adaptive
D) Nonspecific

Accepted Answer

Nonspecific defense mechanisms are directed against all pathogens and foreign agents and include barriers, cellular responses, and inflammation.

Question 6

Which term refers to a protective response to tissue damage that is designed to eliminate pathogens, remove damaged tissues, and create an environment to maximize tissue repair?
A) Anabolism
B) Inflammation
C) Hypersensitivity
D) T cell maturation

Accepted Answer

Inflammation is a protective response to tissue damage resulting from a variety of causes, including infection and trauma. The purpose of inflammation is to eliminate pathogens and foreign agents, remove damaged tissues, and create an environment that maximizes tissue repair.

Question 7

Which term means the body's ability to recognize and respond to pathogens and foreign agents?
A) Filtration
B) Immunity
C) Lymphokinesis
D) Hypersensitivity

Accepted Answer

Immunity is the body's ability to recognize and respond to pathogens and foreign agents. Once exposed to a particular pathogen or foreign agent, the body "remembers" it and launches a quicker attack if the agent enters the body again.

Question 8

Which condition is characterized by abnormal accumulation of fluids within interstitial spaces due to damaged or missing vessels or nodes?
A) Edema
B) Lymphedema
C) Chronic fatigue syndrome
D) Acquired immunodeficiency syndrome

Accepted Answer

Lymphedema is swelling caused by abnormal accumulation of fluids within interstitial spaces because lymphatic vessels or nodes are malformed, damaged, or have been surgically removed.

Question 9

Which condition is a chronic autoimmune, inflammatory disease of the body's connective tissues?
A) Allergies
B) Chronic fatigue syndrome
C) Systemic lupus erythematosus
D) Acquired immunodeficiency syndrome

Accepted Answer

Systemic lupus erythematosus (SLE or lupus) is a chronic autoimmune, inflammatory disease of the body's connective tissues. It leads to the overproduction of circulating autoantibodies. It commonly affects skin, bones, joints, the nervous system, kidneys, lungs, and other organs.

Question 10

Which condition is characterized by an imbalance in the distribution of body fluids but vessels are still intact?
A) Edema
B) Lymphedema
C) Chronic fatigue syndrome
D) Acquired immunodeficiency syndrome

Accepted Answer

Edema is swelling caused by an imbalance in the distribution of body fluids but, unlike in lymphedema, lymphatic vessels are still intact.

Question 11

Which sign is a part of inflammation?
A) Heat
B) Pallor
C) Cyanosis
D) Numbness

Accepted Answer

Heat is a sign of inflammation.

Question 12

Which condition involves altered immunologic responses to otherwise harmless substances?
A) Allergies
B) Chronic fatigue syndrome
C) Systemic lupus erythematosus
D) Acquired immunodeficiency syndrome

Accepted Answer

Allergies are altered immunologic responses to otherwise harmless substances.

Question 13

Which type of cells are involved in cell-mediated immunity?
A) Neutrophils
B) Macrophages
C) T-cells
D) B-cells

Accepted Answer

T-cells are responsible for cell-mediated immunity and they directly attack the invading pathogen or foreign agent.

Question 14

Which condition is a viral infection characterized by progressive impairment of the immune response and increased susceptibility to infections and cancerous tumors?
A) Allergies
B) Chronic fatigue syndrome
C) Systemic lupus erythematosus
D) Acquired immunodeficiency syndrome

Accepted Answer

Acquired immunodeficiency syndrome (AIDS) results from human immunodeficiency virus (HIV) infection and is characterized by progressive impairment of the immune response and increased susceptibility to infections and cancerous tumors.

Question 15

What do B cells produce when they encounter a foreign agent?
A) Macrophages
B) Antibodies
C) Lymphocytes
D) Neutrophils

Accepted Answer

B cells provide surveillance, and when they encounter a foreign agent, produce antibodies. The antibodies attack the foreign agent or direct other immune cells to attack it. This type of response is called antibody-mediated immunity.
