The liver is the body's largest gland.

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.

A. Vagina: The vagina is the canal that leads from the cervix to the outside of the body, not the structure that connects the ovary to the uterus.

B. Uterine tube: The uterine tube, also known as the fallopian tube, connects the ovary to the uterus and is where fertilization typically occurs.

C. Urethra: The urethra is the tube that carries urine from the bladder to the outside of the body. It has no role in connecting the ovary to the uterus.

D. Vas deferens: The vas deferens is a structure in the male reproductive system that transports sperm from the testes. It does not exist in the female reproductive system.
