Question

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

Explanation:

Antidiuretic hormone (ADH), also known as vasopressin, is produced by the hypothalamus and released by the posterior pituitary. It acts on the kidneys to increase water re - absorption. By increasing water re - absorption in the kidneys, it reduces the volume of urine produced. At the same time, as more water is retained in the body, it increases blood volume.

• Nephron stimulating hormone is not a standard recognized hormone in this context.
• Oxytocin is mainly involved in processes like uterine contractions during childbirth and milk ejection during lactation.
• Urine hormone is not a valid scientific term for a known hormone with the described function.
• Natriuretic peptide is involved in processes like promoting sodium excretion and reducing blood pressure, rather than reducing urine volume and increasing blood volume.

Answer:

Antidiuretic hormone
