Question

Glomerular filtrate contains.

• A. Blood without blood cells and proteins
• B. Plasma without sugar
• C. Blood with proteins but without cells
• D. Blood without urea

Answer 1

The correct option is A

Blood without blood cells and proteins

The correct option is A.

Explanations of correct option:

Option A:

1. Glomerular filtration is the process where the toxic waste chemicals and excess fluid are filtered out in the glomerulus in the nephrons of the kidney.
2. The filtrate out from the glomerulus contains nitrogenous waste like ammonia, water, ions, etc., but is devoid of blood cells and major proteins.

Explanations of incorrect options:

Option B:

1. The plasma makes up most of the blood, which is about 55%.
2. Plasma consists of proteins and other blood constituents making up the intravascular part of extracellular fluid (the fluid that surrounds cells) but doesn't include blood cells.
3. As plasma is the liquid part of blood hence it helps to transport sugar.
4. Plasma without sugar exists when the blood glucose level becomes negligible.

Option C:

1. The part of the blood containing proteins without cells is known as blood plasma.
2. Plasma is the liquid part of blood.
3. The proteins present in plasma are known as plasma proteins.

Option D:

1. Blood without urea signifies clean blood free from toxic nitrogenous wastes after complete excretion.
2. Urea-filled blood travels from the liver to the kidney for purification.

Final answer: Glomerular filtrate contains blood without blood cells and proteins.
