OnlineMedEd Shared "Physiology of Digestion and Absorption" - 7 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.
Physiology of Digestion and Absorption
Acinar Cells Release Digestive Enzymes
Ductal Epithelial Cells Release Bicarbonate
Islets of Langerhans
Beta Cells Release Insulin
Alpha Cells Release Glucagon
Delta Cells Release Somatostatin
Somatostatin Inhibits Alpha and Beta Cells
Pancreatin, Pancrelipase (Pancreatic Enzymes)
Inactivated by Gastric Acid
24 Hour Fat Excretion
Take with Every Meal and Snack
Small Intestine Digestion
Brush border enzymes
Pancreatic Enzymes are secreted via a Duct
Pancreas secretes bicarbonate
Brush Border activates Pancreatic Trypsin
Trypsin activates Chymotrypsin
Trypsin and Chymotrypsin digest Proteins
Gallbladder Releases Bile
Pancreatic Lipase breaks down Lipids
Goblet cells secrete mucus
Pancreatic Amylase breaks down Carbohydrates
Pancreatic Nucleases breakdown DNA/RNA
Digestion occurs in the Duodenum
Foregut Structures, Blood Supply and Innervation
Lower Respiratory Tract
Severe Abdominal Pain
High Pitched Bowel Sounds
Absent Bowel Sounds
Types of Intestinal Obstruction
Mesenteric Artery Occlusion
Small Intestine Absorption
Carbohydrates Undergo Active Transport
Amino Acids Undergo Active Transport
Small Lipids Undergo Passive Diffusion
Hepatic Portal Transports Nutrients
Large Lipids Transported as Chylomicrons
Lacteals Transport Chylomicrons
