Which process occurs at the glomerulus?
Red blood cells are removed from the blood.
Water is taken out of the pre-formed urine.
Most of the water is removed from the blood
Nutrients are released to the kidneys.
The Correct Answer is C
A. Red blood cells are removed from the blood: Red blood cells are too large to be filtered at the glomerulus. Only plasma and small molecules pass through.
B. Water is taken out of the pre-formed urine: This happens in later parts of the nephron, such as the collecting ducts, not at the glomerulus.
C. Most of the water is removed from the blood: The glomerulus filters blood, removing water, ions, glucose, and waste products from the bloodstream to form the filtrate.
D. Nutrients are released to the kidneys: Nutrients are filtered into the renal tubules and then reabsorbed, but they are not "released" to the kidneys.
