Q

Intrinsic factor

34
Q

Activity of the stomach is controlled by the _______ nervous system, specifically the _____ nerve.

A

35
Q

What are the three phases of gastric juice production?

A

Cephalic: sensory stimulation stimulates parasympathetic nervous system, which stimulates gastrin release, which stimulates gastric gland activity

Gastric: 2/3 of gastric juices are secreted as food enters stomach and distends stomach walls, which signals stomach to release remaining gastric juices

Intestinal: food enters duodenum. Distention and acidity irritates, stimulating intestinal hormone release which slows gastric juice production until bolus leaves duodenum.

36
Q

37
Q

Describe the activity in the gastric phase of gastric juice production.

A

2/3 of gastric juices are secreted as food enters stomach and distends stomach walls, which signals stomach to release remaining gastric juices

38
Q

Describe the activity which occurs in the intestinal phase of gastric juice production

A

48
Q

What are symptoms of a Hiatal hernia?

A

Lessened ability to take “belly breaths,” expansion of the diaphragm

Potential worsening of GERD, may lead to esophageal ulcers.

49
Q

What three things should be avoided with a hiatal hernia and why?

A

Caffeine, alcohol, smoking–all three of these create tension in the digestive system.
