Question

Substrate which is not filtered through glomerulus is

• A. Plasma
• B. Glucose
• C. Blood corpuscles
• D. Urea

Answer 1

Answer: (C)

Blood corpuscles

The blood flows under glomerulus at greater pressure. Fluid and small solutes are forced under pressure to flow from the glomerulus into the capsular space of the glomerular capsule. The Bowman's capsule is the filtration unit of the glomerulus. Blood entering the glomerulus has filterable and nonfilterable components. Filterable blood components include water, nitrogenous waste, and nutrients and will be transferred into the glomerulus to form the glomerular filtrate. Non-filterable blood components include blood cells and platelets remain in the arteriole. The size of the filtration slits restricts the passage of large molecules (eg, albumin) and cells (eg, red blood cells and platelets) into the renal tubules.

So, the correct answer is option C.
