Study Notes
Paneth Cells
- A reduction in the number of Paneth cells would likely have significant consequences.
Goblet Cells
- The jejunum has the most goblet cells in the digestive tract.
Anatomy of the Duodenum
- The hepatic portal vein crosses over the inferior or horizontal (third) portion of the duodenum.
Hormonal Imbalance
- An imbalance of secretin would result in an acidic small intestine environment, despite normal levels of pancreatic enzymes, pepsinogen, and stomach and gall bladder motility.
Anatomy of the Pancreas
- The tail of the pancreas lies in the splenic hilum.
- The splenic artery supplies blood to the pancreas.
- The pancreatic head is responsible for secreting enzymes via a duct or ducts into the superior part of the duodenum.
Salivary Gland Damage
- Damage to the parotid gland would lead to an increase in the concentration of triglycerides in the esophagus.
Steatorrhea Causes
- The liver is the least likely organ to be the cause of a patient's steatorrhea.
Abdominal Pain Causes
- The most likely cause of a 68-year-old man's acute-onset severe upper abdominal pain is gallstones.
