Amino acids and monosaccharides are absorbed in the______________ and fatty acids are absorbed in the_____________

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. Mucosa (mucous membrane): The mucosa is the innermost layer of the digestive tract, not the outermost. It includes the epithelium, lamina propria, and muscularis mucosae.

B. Serosa (mesentery): The serosa is the outermost layer of the digestive tract in parts where it is covered by peritoneum. It consists of a thin layer of areolar tissue topped by simple squamous epithelium.

C. Muscularis externa: The muscularis externa is a layer of muscle in the digestive tract, located beneath the serosa. It is not the outermost layer.

D. Submucosa: The submucosa is a layer of connective tissue located between the mucosa and muscularis externa. It is not the outermost layer.
