The large intestine absorbs water, fats, and salts.

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. Metabolic water; cutaneous transpiration: Metabolic water refers to the water produced during metabolic processes within the body. However, most body water intake comes from drinking fluids, not metabolic water.

B. Drinking; cutaneous transpiration and expired air: While drinking is indeed the main source of water intake, the greatest loss of water from the body is through urine, not cutaneous transpiration and expired air.

C. Drinking; radiation: While drinking is the primary source of water intake, radiation is not a significant way the body loses water.

D. Drinking; urine: Drinking fluids is the main source of water intake, and urine excretion is the primary way the body loses water.
