Q: Which equation correctly represents the net filtration pressure (NFP) in the glomerulus?

NFP = $$\text{HP}_{\text{gc}} - (\text{HP}_{\text{cs}} + \text{OP}_{\text{gc}})$$

Question 1

Which of the following best describes the function of lacteals in the lymphatic system?

Accepted Answer

They absorb dietary fats from the small intestine and transport them to the bloodstream.

Question 2

A patient presents with swollen, tender lymph nodes (buboes) after a bacterial infection. Which of the following best explains the cause of this swelling?

Accepted Answer

Blockage of efferent lymphatic vessels causing lymph to accumulate.

Question 3

Which of the following statements about the right lymphatic duct and thoracic duct is correct?

Accepted Answer

The thoracic duct returns lymph to the venous circulation at the junction of the left subclavian and internal jugular veins.

Question 4

Which of the following is a primary lymphoid organ, and what is its main function?

Accepted Answer

Thymus; site of T cell maturation and selection.

Question 5

During an inflammatory response, which of the following is NOT a typical sign?

Accepted Answer

Loss of consciousness

Question 6

Which of the following best describes the role of C3b in the complement system?

Accepted Answer

C3b acts as an opsonin, enhancing phagocytosis of pathogens.

Question 7

A patient receives a vaccine and develops immunity. Which type of immunity is this?

Accepted Answer

Active, artificially acquired immunity

Question 8

Which of the following best explains why the thymus is unique among lymphoid organs?

Accepted Answer

It does not directly fight antigens but is essential for T cell maturation.

Question 9

Which equation correctly represents the net filtration pressure (NFP) in the glomerulus?

Accepted Answer

NFP = $$	ext{HP}_{	ext{gc}} - (	ext{HP}_{	ext{cs}} + 	ext{OP}_{	ext{gc}})$$

Question 10

Which of the following is TRUE regarding the difference between cortical and juxtamedullary nephrons?

Accepted Answer

Juxtamedullary nephrons have longer nephron loops that extend deep into the medulla, allowing for greater concentration of urine.

Question 11

A patient with a deficiency in MHC class II proteins would most likely have impaired activation of which cell type?

Accepted Answer

CD4 helper T cells

Question 12

Which of the following is a correct sequence for the steps of phagocytosis?

Accepted Answer

Adherence → Ingestion → Digestion → Exocytosis

Question 13

Which of the following best describes the difference between obligatory and facultative water reabsorption in the nephron?

Accepted Answer

Obligatory water reabsorption occurs in the proximal convoluted tubule, while facultative occurs in the collecting duct under the influence of ADH.

Question 14

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

Accepted Answer

Production of urine

Question 15

Which of the following best describes the role of antigen presenting cells (APCs) in the adaptive immune response?

Accepted Answer

APCs present processed antigens on MHC molecules to T cells, initiating their activation.

Question 16

Which of the following is TRUE regarding the two routes of tubular reabsorption in the nephron?

Accepted Answer

Transcellular route involves movement through the cell, while paracellular route involves movement between cells.

Question 17

A patient with autoimmune disease is experiencing tissue damage due to the immune system attacking self-antigens. Which of the following best explains this phenomenon?

Accepted Answer

Failure of negative selection during lymphocyte maturation, leading to self-reactive cells.

Question 18

Which of the following correctly matches the region of the lymph node with its primary function?

Accepted Answer

Cortex: houses B cells and initiates immune responses

Question 19

Which of the following is TRUE regarding the difference in urethra between males and females?

Accepted Answer

The male urethra is longer and serves both urinary and reproductive functions.

Question 20

Which of the following best describes the process of micturition?

Accepted Answer

It is the voluntary and involuntary process of emptying the bladder, involving contraction of the detrusor muscle and relaxation of the internal and external sphincters.
