Direct regulation of blood pH via secretion of H\textsuperscript{+}

Question 1

Which of the following is NOT a primary function of the kidney?

Accepted Answer

Direct regulation of blood pH via secretion of H	extsuperscript{+}

Question 2

Filtration in the nephron occurs primarily due to which physical force?

Accepted Answer

Hydrostatic pressure in the glomerulus

Question 3

A patient is experiencing high blood pressure. Which renal mechanism is most likely to respond to decrease glomerular filtration rate (GFR)?

Accepted Answer

Constriction of the afferent arteriole

Question 4

Which equation best represents the calculation of Glomerular Filtration Rate (GFR)?

Accepted Answer

$$GFR = P_{GC} - P_{BS} - \pi_{GC}$$

Question 5

Which of the following is a correct description of the process of absorption in the digestive system?

Transfer of nutrients from the GI lumen into blood

Question 6

Which cells in the stomach are responsible for secreting gastrin?

Accepted Answer

G cells

Question 7

A patient has a deficiency in pancreatic amylase. Which digestive process will be most affected?

Accepted Answer

Digestion of carbohydrates

Question 8

Which of the following best describes the role of GALT (gut-associated lymphoid tissue)?

Accepted Answer

Provides immune protection in the GI tract

Question 9

Which type of immunity involves T cells and is cell-mediated?

Accepted Answer

Adaptive immunity

Question 10

Which immune cells are primarily responsible for phagocytosis?

Accepted Answer

Neutrophils and macrophages

Question 11

A patient is exposed to a virus for the first time. Which immune response is most likely to occur?

Accepted Answer

Innate immune response involving phagocytes and inflammation

Question 12

Which of the following is TRUE regarding MHC molecules?

Accepted Answer

MHC molecules are essential for antigen presentation to T cells

Question 13

Which process is responsible for the generation of antibody diversity?

Accepted Answer

A male patient has a mutation in the SRY gene. Which of the following is most likely to occur?

Accepted Answer

Development of ovaries

Question 16

Which structure is the site of fertilization in the female reproductive system?

Accepted Answer

Fallopian tube

Question 17

Which of the following best describes the role of the Leydig cells in the testes?

Accepted Answer

Secrete testosterone

Question 18

A patient has a blockage in the efferent arteriole of the nephron. What is the most likely effect on glomerular filtration rate (GFR)?

Accepted Answer

GFR will increase due to increased hydrostatic pressure in the glomerulus

Question 19

Which of the following is a correct sequence for the passage of an ovum from the ovary to the uterus?

Accepted Answer

Ovary → Fallopian tube → Uterus

Question 20

Which of the following best explains why the bladder only stores urine and does not produce it?

Accepted Answer
