|
elevated blood pressure
|
|
|

|
|
|
cardiovascular shock

|
|
b and c
|

|
all of the above

Explanation:
Detailed explanation-1: -So, the correct answer is ‘An increase in afferent arteriolar pressure’.
Detailed explanation-2: -The forces that govern filtration in the glomerular capillaries are the same as any capillary bed. Capillary hydrostatic pressure (Pc) and Bowman’s space oncotic pressure (i) favor filtration into the tubule, and Bowman’s space hydrostatic pressure (Pi) and capillary-oncotic pressure (c) oppose filtration.
Detailed explanation-3: -The diameter of afferent arteriole is larger than the efferent arteriole. This increases the volume of blood in glomerulus and increases the filtration rate. This causes the effective filtration pressure which is the total pressure that promotes filtration.
