Question 1

Which of the following best describes the difference between innate and adaptive immunity?

Accepted Answer

Innate immunity provides a rapid, non-specific response, while adaptive immunity provides a slower, specific response.

Question 2

During inflammation, which sequence correctly describes the cause-and-effect process?

Accepted Answer

Tissue injury → release of histamine → vasodilation → increased capillary permeability → migration of phagocytes

Question 3

Which antibody is most important for guarding mucosal membranes?

Accepted Answer

IgA

Question 4

A patient receives an injection of antibodies against rabies after being bitten by a potentially rabid animal. This is an example of:

Accepted Answer

Artificial passive immunity

Question 5

Which of the following best describes the primary immune response compared to the secondary immune response?

Accepted Answer

The primary response involves naive B cells, while the secondary response involves memory B cells and is faster and stronger.

Question 6

Which equation best represents Boyle’s Law as it applies to pulmonary ventilation?

Accepted Answer

$$P_1$$ $$V_1$$ = $$P_2$$ $$V_2$$

Question 7

During inhalation, which of the following occurs?

Accepted Answer

The diaphragm contracts, thoracic volume increases, and air moves into the lungs.

Question 8

A pneumothorax occurs when:

Accepted Answer

Air enters the pleural cavity, causing lung collapse due to loss of negative pressure.

Question 9

Which equation best represents Dalton’s Law as it relates to respiratory gas exchange?

Accepted Answer

$$P_{total} = P_1$ + P_2$ + P_3$ + \ldots$$

Question 10

Which factor would most likely decrease hemoglobin saturation in the blood?

Accepted Answer

Increased CO$$_2$$ concentration

Question 11

Which of the following is a primary function of the liver in digestion?

Accepted Answer

Producing bile to emulsify fats

Question 12

Which process is responsible for moving food through the esophagus?

Accepted Answer

Peristalsis

Question 13

Which of the following best describes the difference between short and long reflex arcs in the digestive system?

Accepted Answer

Short reflex arcs are limited to the enteric nervous system, while long reflex arcs involve the central nervous system.

Question 14

Which enzyme is primarily responsible for the digestion of carbohydrates in the small intestine?

Accepted Answer

Pancreatic amylase

Question 15

Which layer of the GI tract is most responsible for absorption of nutrients?

Accepted Answer

Mucosa

Question 16

Which of the following best describes the difference between catabolic and anabolic processes?

Accepted Answer

Catabolic processes break down complex molecules into simpler ones, releasing energy; anabolic processes build complex molecules from simpler ones, requiring energy.

Question 17

During the absorptive state, which of the following events occurs?

Accepted Answer

Glucose is taken up by cells and stored as glycogen.

Question 18

Which of the following is a monomer of proteins?

Accepted Answer

Amino acid

Question 19

Which pathway correctly traces the maturation of a lymphocyte?

Accepted Answer

Stem cell → immunocompetence → self-tolerance → seeding → clonal selection → proliferation and differentiation

Question 20

Which outcome can occur when an antibody-antigen complex forms?

Accepted Answer

Activation of complement, leading to cell lysis
