Alimentary Canal
Most nutrient absorption occurs in this organ.
What is the small intestine?
The liver produces this digestive fluid.
What is bile?
The pancreas secretes digestive enzymes into this part of the small intestine.
What is the duodenum?
The first part of the large intestine is called this.
What is the cecum?
The stomach connects the esophagus to this organ.
What is the duodenum?
The muscular movement that propels food through the GI tract is called this.
What is peristalsis?

What is the gallbladder?
The main duct carrying pancreatic secretions is called this.
What is the pancreatic duct?
These pouch-like structures give the colon its segmented appearance.
What are haustra?

What are proteins?
This valve separates the stomach from the duodenum.
What is the pyloric sphincter?

What are fats (lipids)?
Bicarbonate helps raise the pH of this material entering the duodenum.
What is chyme?

What are the mucosa, submucosa, muscularis externa, and serosa (or adventitia)?

What is the hepatic portal vein?
The inactive forms of digestive enzymes help prevent this dangerous condition.

The large intestine absorbs this vitamin produced by intestinal bacteria.
What is vitamin K?
The folds in the stomach wall that allow expansion are called these.
What are rugae?
A patient has damage to the villi of the small intestine. Explain the major physiological consequences.
What are decreased nutrient absorption and malnutrition (or weight loss, vitamin deficiencies, diarrhea)?
Bile salts are synthesized from this lipid.
What is cholesterol?
The pancreatic secretion stimulated by secretin is rich in this substance but low in digestive enzymes.
What is bicarbonate?
The sympathetic nervous system generally has this effect on colonic motility.
What is decreasing motility?
A patient lacking parietal cells would have difficulty absorbing this vitamin.
What is vitamin B₁₂?
