Lactase is made
Small bowel
Nuclease is made
Pancreas
Chief Cells make
Pepsin (ogen)
Goblet Cells make
Mucus
Parietal Cells make (2)
HCl (acid in stomach)

Intrinsic Factor (needed to absorb Vit B12

Functions of HCl (4)
Kills bacteria, breaks down plant cell walls, denatures protein, activates pepsin
Intrinsic factor is made
Parietal Cells - stomach
Intrinsic factor function
Required for absorption of vitamin B-12
What activates Pepsin
HCl in stomach
What activates Trypsin
Enterokinase
What activates Chymotrypsin
Trypsin
What activates Carboxypeptidase
Trypsin
What controls Salivary Amylase?
Parasympathetic Nervous System
What controls pepsin?
Parasympathetic Nervous System and Gastrin
What controls Enterokinase?
Food in contact with small bowel
What controls Trypsin
CCK (cholecystokinin)
What controls Chymotrypsin?
CCK (cholecystokinin)
What controls Carboxypeptidase?
CCK (cholecystokinin)
What controls Pancreatic Amylase?
CCK (cholecystokinin)
What controls Maltase?
Food in contact with small bowel
What controls Lactase?
Food in contact with small bowel
What controls Lipase?
CCK (cholecystokinin)
What controls Nuclease?
CCK (cholecystokinin)
Effect of CCK (3)
1. Decreases gastric activity 2. Stimulates release of bile from gall bladder 3. Stimulates release of digestive enzymes from pancreas
Effect of Secretin
Stimulates HCO3- release from pancreas
Effect of Gastrin
Increases gastric activity
Enterogastric reflex (source-target-effect)
From Small Bowel to Stomach, decrease activity
Gastroenteric reflex (source-target-effect)
From Stomach to small bowel, increase small bowel motility
Gastroileal reflex (source-target-effect)
From Stomach to Ileum, Increase motility in ileum, open ileocecal valve
Gastrocolic reflex (source-target-effect)
From Stomach to colon, cause mass movement in colon (increase motility)
Effect of Salivary amylase?
Starches-> disaccharides
Effect of Pepsin
Proteins->peptides
Effect of pancreatic amylase
Starches-> disaccharides
Effect of Carboxypeptidase
Peptides to amino acids
Effect of Pancreatic Lipase
Fats (triglycerides to glycerol and fatty acids)
Effect of Trypsin
Peptides to amino acids
Effect of Chymotrypsin
Peptides to amino acids
Effect of Enterokinase
Activates Trypsin
Effect of Maltase
Disaccharides to monosaccharides
Effect of Lactase
Disaccharides to monosaccharides
Effect of nuclease
DNA, RNA -> nucleotides

What anatomical changes are found in the small bowel to increase absorption? (3 answers)

1. Circular Folds


2. Villi


3. Microvilli




All increase surface area, and so increase absorption.

What nutrients are found in the hepatic portal vein?

Sugars, Amino acids, but NOT FATS (they go into the lacteals -> lymphatic system)

How are fats transported from the small bowel?

They do NOT go into the hepatic portal vein. They are transported via the lymphatic system->Thoracic Duct -> Left Subclavian
