Question 1

A patient presents with a bacterial infection. Which leukocyte type would you expect to be most elevated in their blood count, and what is its primary function?

Accepted Answer

Neutrophils; act as active phagocytes during acute infections

Question 2

During a routine blood test, a patient's hematocrit is measured at 60%. Which of the following best describes what this value represents?

Accepted Answer

The percentage of erythrocytes in the blood

Question 3

A person suffers a deep cut. Which sequence correctly describes the phases of hemostasis that will occur to stop the bleeding?

Accepted Answer

Vascular spasms → Platelet plug formation → Coagulation

Question 4

Which of the following best explains why the left ventricular wall is thicker than the right ventricular wall?

Accepted Answer

It pumps blood to the entire body, requiring greater force

Question 5

A patient has a blockage in their right lymphatic duct. Which region of the body would most likely experience lymphatic fluid buildup (edema)?

Accepted Answer

Right arm

Question 6

Which heart sound ('Lub' or 'Dup') is associated with the closing of the semilunar valves, and during which phase of the cardiac cycle does this occur?

Accepted Answer

'Dup'; at the end of ventricular systole

Question 7

A patient with a genetic deficiency in albumin production would most likely experience which of the following symptoms, and why?

Accepted Answer

Edema due to decreased plasma osmotic pressure

Question 8

Which of the following best describes the mechanism by which lymph is propelled through lymphatic vessels?

Accepted Answer

Contraction of skeletal muscles and thoracic pressure changes

Question 9

A patient is diagnosed with a deficiency in T lymphocyte maturation. Which lymphoid organ is most likely malfunctioning?

Accepted Answer

Thymus

Question 10

Which equation correctly represents Boyle's Law as it applies to pulmonary ventilation?

Accepted Answer

$$P_1V_1 = P_2V_2$$

Question 11

A patient with a mutation affecting fibrinogen production would most likely have difficulty with which phase of hemostasis?

Accepted Answer

Coagulation

Question 12

Which of the following best describes the role of the spleen in the lymphatic and circulatory systems?

Accepted Answer

It filters blood, destroys worn-out erythrocytes, and stores platelets

Question 13

A patient is experiencing muscle weakness due to impaired calcium binding in muscle fibers. Which physiological process is most directly affected?

Accepted Answer

Sliding filament theory of muscle contraction

Question 14

Which of the following correctly matches the leukocyte with its function?

Accepted Answer

Eosinophils: attack parasitic worms and mediate allergy response

Question 15

A patient with chronic respiratory acidosis has a blood pH of 7.25. How does this compare to the normal blood pH range, and what does it indicate?

Accepted Answer

It is below the normal range; indicates acidosis

Question 16

Which of the following best explains why lymph nodes have more afferent than efferent vessels?

Accepted Answer

To slow lymph flow for thorough filtration

Question 17

A patient is unable to clear bacteria from their digestive tract, leading to frequent infections. Which lymphoid structure is most likely compromised?

Accepted Answer

Peyer's patches

Question 18

Which of the following best describes the main function of the cardiovascular system's pulmonary circuit?

Accepted Answer

Deliver oxygen-poor blood to the lungs for gas exchange

Question 19

Which formula correctly represents the calculation of cardiac output ($$CO) in $$terms of heart rate ($$HR) $$and stroke volume ($$SV$$)?

Accepted Answer

$$CO = HR 	imes SV$$

Question 20

A patient with a mutation that prevents the production of globulins would most likely have which of the following problems?

Accepted Answer

Impaired antibody-mediated immunity
