The appearance of alubumin in the urine is most likely due to `:`

Options

A. Increase in the blood pressure
B. Decrease in the blood osmotic pressure
C. Damage to the Malpighian corpuscles
D. Damage to the proximal convoluted tubules

Answer

B

Explanation

The glomerular basement membrane does not usually allow passage of albumin and large proteins. A small amount of albumin usually less than 25 mg/ 24 hrs is found in urine.
A pigment that causes the yellow colour in urine sis urochrome. It is a breakdown product of the blood’s hemoglobin and is removed by the kidneys. When large amount in excess of 250 mg/ 24 hrs are detected significant damage to glomerular membrane has occurred.
