Question

which pituitary hormone reduces urine volume and increases blood volume?
multiple choice
oxytocin
urine hormone
antidiuretic hormone
natriuretic peptide
nephron stimulating hormone

Explanation:

• Oxytocin is involved in childbirth and lactation, not urine/blood volume regulation.
• "Urine hormone" is not a recognized pituitary hormone.
• Antidiuretic hormone (ADH) acts on the kidneys to reabsorb water, reducing urine volume and increasing blood volume.
• Natriuretic peptides increase urine output and decrease blood volume.
• "Nephron stimulating hormone" is not a valid pituitary hormone.

Answer:

C. Antidiuretic hormone
