The appearance of albumin in the urine, is most likely due to
Increase in the blood pressure
Decrease in the blood osmotic pressure
Damage to the Malpighian corpuscles
Damage to the proximal convoluted tubules
The correct option is C Damage to the Malpighian corpuscles
The normal urinary excretion of albumin is less than 30 mg/day. An increase in urinary albumin excretion is indicative of increased permeability of the filtering cells of the kidney in the glomerulus, which is a part of Malpighian corpuscle of the kidney. Albuminuria is the presence of albumin in the urea.
So, the correct answer is option C.
