Secretin. The small intestine is periodically assaulted by a flood of acid from the stomach, and it is important to put out that fire in a hurry to avoid acid burns. similar, but quantitatively less important response to secretin is elicited by bile duct cells, resulting in additional bicarbonate being dumped into the small gut. As acid is neutralized by bicarbonate, the intestinal pH rises toward neutrality, and secretion of secretin is turned off.

The findings shatter a widespread belief among experts and laymen alike in the primacy of family influence and are sure to engender fierce debate.nother highly inherited trait, though one not commonly thought of as part of personality, was the capacity for becoming rapt in an aesthetic experience, such as a concert. Vulnerability to stress, as measured on the Tellegen test, reflects what is commonly thought of as ''neuroticism,'' according to Dr. Lykken.
