In the nephron, the fluid that immediately precedes urine is known as:
renal filtrate
tubular fluid
plasma
glomerular filtrate
The Correct Answer is B
A. Renal filtrate refers to the fluid filtered from the blood in the glomerulus, which is the initial stage of urine formation. It does not immediately precede urine.
B. Tubular fluid is the filtrate as it passes through the nephron tubules, undergoing various processes like reabsorption and secretion. This fluid eventually becomes urine, after the final adjustments in the collecting duct.
C. Plasma is the liquid component of blood that is filtered by the glomerulus, but it is not the direct precursor to urine.
D. Glomerular filtrate is the fluid filtered out of the blood in the glomerulus and is the precursor to tubular fluid, not directly to urine.

Correct Answer is B
Explanation
A. It stimulates angiotensin II secretion: Antidiuretic hormone (ADH) does not directly stimulate angiotensin II secretion; instead, it acts on the kidneys to promote water reabsorption.
B. It promotes water conservation: ADH promotes water conservation by increasing water reabsorption in the kidneys, reducing urine output, and thus helping to maintain fluid balance.
C. It inhibits salivation and thirst: ADH does not inhibit salivation or thirst; in fact, it can increase thirst to encourage fluid intake when dehydration is detected.
D. It stimulates hypothalamic osmoreceptors: While ADH affects hypothalamic osmoreceptors indirectly by promoting water retention, its primary function is to act on the kidneys to conserve water.
