Answer

Liver disease

Answer

Bronchitis

Answer

Pneumonia

Question 7

In the context of cellular adaptation, what is the primary difference between hypertrophy and hyperplasia?

Accepted Answer

Hypertrophy involves increased cell size, while hyperplasia involves increased cell number.

Answer

Hypertrophy involves increased cell number, while hyperplasia involves increased cell size.

Answer

Hypertrophy is pathological, while hyperplasia is always physiological.

Answer

Hypertrophy is irreversible, while hyperplasia is reversible.

Accepted Answer

C. Fever

Answer

A. Mucous membranes

Answer

B. Cilia

Answer

D. Nasal hairs

Question 9

Dendritic cells are responsible for presenting antigens to T-helper cells, thereby initiating the adaptive immune response.

Accepted Answer

True

Answer

False

Question 10

Which of the following characteristics is unique to the adaptive immune system compared to the innate immune system?

Accepted Answer

B. Immunological memory

Answer

A. Immediate response time

Answer

C. Non-specific recognition

Answer

D. Physical barrier function

Question 11

Which of the following are considered physical barriers that prevent the entry of pathogens into the body?

Answer

A. Skin

Answer

B. Mucous membranes

Answer

C. Cilia

Answer

D. Fever

Question 12

Which specific cell type differentiates into plasma cells to produce antibodies?

Accepted Answer

B lymphocytes

Question 13

What is the primary function of antibodies in the immune response?

Accepted Answer

A. Binding to specific antigens to mark them for destruction

Answer

B. Directly engulfing pathogens via phagocytosis

Answer

C. Presenting antigens to B cells

Answer

D. Producing histamine to trigger inflammation

Question 14

Which primary mediator is released during the degranulation of mast cells in a Type 1 hypersensitivity reaction?

Accepted Answer

Histamine

Answer

Complement C3b

Answer

Interferon-gamma

Answer

IgG antibodies

Question 15

What is the primary mechanism of action of adrenaline in the emergency treatment of anaphylaxis?

Accepted Answer

Stabilization of mast cell membranes and vasoconstriction

Answer

Inhibition of IgE production

Answer

Neutralization of circulating histamine

Answer

Suppression of T-cell proliferation

Question 16

Primary immunodeficiency disorders are typically acquired through external factors such as malnutrition or chronic viral infections.

Accepted Answer

False

Answer

True

Question 17

Which of the following are recognized causes of secondary immunodeficiency?

Answer

Chronic corticosteroid therapy

Answer

Severe protein-calorie malnutrition

Answer

Chemotherapy-induced bone marrow suppression

Answer

Genetic mutation in B-cell maturation

Question 18

What is the specific role of MHC (Major Histocompatibility Complex) self-markers in the context of immune tolerance?

Accepted Answer

MHC markers allow the immune system to recognize host cells as 'self', preventing the activation of autoreactive T-cells.

Question 19

In Type 1 Diabetes, which specific cells are destroyed by the immune system due to a failure in self-tolerance?

Accepted Answer

Pancreatic beta cells

Answer

Pancreatic alpha cells

Answer

Hepatocytes

Answer

Renal tubular cells

Question 20

Define the sensitization phase in a Type 1 hypersensitivity reaction.

Accepted Answer

The initial exposure to an allergen that triggers B-cells to produce IgE antibodies, which then bind to the surface of mast cells and basophils.
