Question 1

Which of the following best describes the process of opsonization in the immune response?

Accepted Answer

The action of some antibodies to stick to microbes, making the microbes more susceptible to phagocytosis.

Question 2

Which term describes a cell that develops from a monocyte, leaves the blood, and migrates to infected tissues?

Accepted Answer

Wandering macrophage

Question 3

Chemotaxis in the immune system refers to:

Accepted Answer

Attraction of phagocytes to microbes by a chemical stimulus.

Question 4

What is the result of filtration exceeding reabsorption in tissue capillaries?

Accepted Answer

Abnormal accumulation of interstitial fluid within tissues, known as edema.

Question 5

Which of the following is a type of adaptive immunity that mostly involves B-cells that secrete antibodies?

Accepted Answer

Humoral immunity

Question 6

Immunoglobulins are:

Accepted Answer

Synthesized by plasma cells derived from B lymphocytes in response to the introduction of an antigen.

Question 7

Which of the following best describes antigen-presenting cells (APCs)?

Accepted Answer

A group of immune cells that process and present antigens for recognition by T cells to initiate the adaptive cellular immune response.

Question 8

What is the name for the fluid found within lymphatic vessels that resembles interstitial fluid?

Accepted Answer

Lymph

Question 9

Type II alveolar cells are important in the respiratory system because they:

Accepted Answer

Produce surfactant which prevents alveoli from collapse.

Question 10

Which of the following is an example of a chemical barrier in the body's first line of defense?

Accepted Answer

Tears, saliva, and vaginal secretions all contain an antibacterial agent which washes away or destroys pathogens.

Question 11

Which structure is responsible for dumping lymph into the left subclavian vein?

Accepted Answer

Cisterna chyli

Question 12

Which of the following best describes lymph nodes?

Accepted Answer

Filtering bean-shaped structures located along lymphatic vessels.

Question 13

Which of the following is a specialized lymph tissue found in mucous membranes?

Accepted Answer

MALT (Mucosa-associated lymphoid tissue)

Question 14

A patient presents with swelling in their lower limbs due to abnormal accumulation of interstitial fluid. Which of the following best explains this condition?

Accepted Answer

Filtration exceeds reabsorption, leading to edema.

Question 15

Which of the following is NOT a function of the spleen?

Accepted Answer

Production of surfactant for the lungs.

Question 16

Which of the following best describes the role of chemotaxis in inflammation?

Accepted Answer

It attracts phagocytes to the site of infection by a chemical stimulus.

Question 17

Which of the following is a correct sequence of events in the adaptive immune response?

Accepted Answer

Antigen presentation → Activation of T cells → Activation of B cells → Antibody production

Question 18

Which of the following equations best represents the Starling equation for net filtration pressure ($NFP$) in capillaries?

Accepted Answer

$NFP = (P_c - P_i) - (\pi_c - \pi_i)$

Question 19

A patient with a genetic deficiency in type II alveolar cells would most likely experience which of the following complications?

Accepted Answer

Increased risk of alveolar collapse due to lack of surfactant.

Question 20

Which of the following best explains why lymph resembles interstitial fluid?

Accepted Answer

Lymph is derived from interstitial fluid that enters lymphatic capillaries.

Question 21

Which of the following is a primary function of MALT (mucosa-associated lymphoid tissue)?

Accepted Answer

To provide immune defense against pathogens entering through mucous membranes.
