Available products offer different levels of detail, scale, labeling, mounting, and removable components for introductory through advanced instruction.
Study the Anatomy of the Human Digestive System
The digestive system includes a continuous muscular passage extending from the mouth to the anus, along with accessory organs that support digestion. Anatomical models help learners examine the position, shape, structure, and relationships of these organs within the head, neck, chest, abdomen, and pelvis.
Depending on the model selected, students may be able to identify the oral cavity, teeth, tongue, salivary glands, pharynx, esophagus, stomach, small intestine, large intestine, rectum, liver, gallbladder, pancreas, appendix, and associated ducts and blood vessels.
Three-dimensional digestive models help demonstrate how food travels through the gastrointestinal tract and how digestive organs work together to mechanically and chemically process nutrients.
Complete Digestive System Models
Complete digestive system models provide an overview of the gastrointestinal tract and accessory digestive organs. These models may show the digestive pathway from the mouth and esophagus through the stomach, small intestine, large intestine, rectum, and anus.
Depending on the product, accessory structures may include the salivary glands, liver, gallbladder, pancreas, spleen, blood vessels, and portions of the diaphragm or abdominal wall. Some models are mounted on a board or base, while others contain removable sections for closer study.
Complete digestive system displays are useful for anatomy, physiology, biology, nursing, medical, dietetics, and patient education.
Dissectible Digestive Models with Removable Parts
Dissectible digestive models separate into removable components so learners can examine individual organs and internal structures. Depending on the model, removable parts may include the stomach, liver, gallbladder, pancreas, intestines, appendix, or sections of the abdominal wall.
Students can remove and replace structures while practicing identification and learning how the digestive organs fit together inside the abdominal cavity. This hands-on approach supports anatomy instruction without requiring preserved biological specimens.
The number of removable components varies by product. Review each model’s specifications for the included organs, internal details, mounting style, and assembly features.
Oral Cavity, Teeth, and Salivary Gland Models
Digestion begins in the mouth, where food is mechanically broken down and mixed with saliva. Models of the oral cavity may show the teeth, tongue, hard palate, soft palate, salivary glands, pharynx, and surrounding muscles.
Depending on the product, the parotid, submandibular, and sublingual glands may be represented along with their ducts. These structures help learners understand the role of saliva in lubrication, swallowing, and the initial chemical digestion of food.
Oral digestive models are useful for anatomy, dental, medical, nursing, speech-language pathology, and nutrition education.
Esophagus and Swallowing Anatomy
The esophagus is a muscular tube that carries swallowed material from the pharynx to the stomach. Head, neck, torso, and digestive system models may show its relationship to the trachea, heart, diaphragm, and surrounding structures.
Sectioned models can help students follow the pathway of food during swallowing and understand how the esophagus passes through the thoracic cavity before entering the stomach.
Models showing the pharynx and upper digestive tract can also support instruction involving swallowing disorders, reflux, airway protection, and clinical assessment.
Human Stomach Models
Stomach models provide a focused view of the organ responsible for storing food, mixing it with gastric secretions, and beginning the digestion of proteins. Depending on the model, learners may be able to identify the cardia, fundus, body, pyloric region, greater curvature, lesser curvature, and connections with the esophagus and duodenum.
Dissectible or sectioned stomach models may reveal internal folds, muscular layers, mucosal structures, blood vessels, and openings leading into and out of the organ.
Enlarged models may also show the microscopic organization of the stomach wall, including gastric pits, glands, epithelial tissue, smooth muscle, and surrounding membranes.
Stomach Wall and Gastric Mucosa Models
Enlarged stomach wall models help learners examine tissue layers that are difficult to see on a complete organ model. These may include the mucosa, submucosa, muscular layers, serosa, gastric pits, glands, blood vessels, and nerves.
Models of gastric microanatomy connect gross digestive anatomy with histology and physiology. They can help explain how the stomach produces acid, enzymes, mucus, and muscular contractions during digestion.
These models are useful for anatomy, physiology, histology, medical, nursing, and biology education.
Small Intestine Models
The small intestine is the primary location for chemical digestion and nutrient absorption. It consists of the duodenum, jejunum, and ileum. Digestive system models may show these regions as part of the complete gastrointestinal tract or as enlarged specialized structures.
Depending on the model, learners may be able to examine the intestinal wall, circular folds, villi, microvilli, lymphatic vessels, capillaries, and muscular layers involved in digestion and absorption.
Models of the small intestine help explain how nutrients move from the digestive tract into the bloodstream and lymphatic system.
Intestinal Villi and Absorption Models
Intestinal villi are small projections that increase the absorptive surface area of the small intestine. Enlarged villus models may show epithelial cells, blood capillaries, lacteals, connective tissue, glands, and surrounding intestinal structures.
These models make microscopic absorption anatomy visible during classroom demonstrations. They help students understand how carbohydrates, proteins, fats, vitamins, minerals, and water are transferred from the intestine into the body.
Villus and intestinal wall models are useful for anatomy, physiology, nutrition, biology, nursing, and medical education.
Large Intestine and Colon Models
The large intestine absorbs water and electrolytes, houses intestinal microorganisms, compacts waste, and stores fecal material before elimination. Models may show the cecum, appendix, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal.
Depending on the product, learners may also be able to identify the ileocecal junction, haustra, teniae coli, epiploic appendages, mesentery, blood vessels, and internal wall structures.
Colon models are useful for anatomy, nursing, gastroenterology, surgical education, patient consultations, and instruction involving colorectal screening.
Appendix and Ileocecal Region Models
The appendix extends from the cecum near the junction between the small and large intestines. Digestive models may show its position relative to the terminal ileum, cecum, ascending colon, and surrounding abdominal structures.
Sectioned models can help explain inflammation, obstruction, and the anatomical basis of appendicitis. The amount of detail represented varies by product.
Liver Anatomy Models
The liver is a major accessory digestive organ involved in metabolism, detoxification, nutrient processing, bile production, and storage. Liver models may show the right and left lobes, inferior surface, porta hepatis, blood vessels, bile ducts, gallbladder, and surrounding structures.
Depending on the product, removable or sectioned models may reveal internal vessels, hepatic segments, bile drainage, or the relationship between the liver, diaphragm, stomach, pancreas, and intestines.
Liver models support education in anatomy, medicine, nursing, surgery, gastroenterology, nutrition, and patient care.
Liver Lobule and Microanatomy Models
Liver lobule models provide an enlarged view of the microscopic structural units of the liver. These models may show hepatocytes, central veins, sinusoids, portal areas, bile canaliculi, arteries, veins, and bile ducts.
Enlarged microanatomy models help students understand the relationship between liver structure and functions such as blood filtration, metabolism, bile production, and detoxification.
These models are useful for anatomy, physiology, histology, medical, nursing, and biology instruction.
Gallbladder and Bile Duct Models
The gallbladder stores and concentrates bile produced by the liver. Models may show the gallbladder, cystic duct, common hepatic duct, common bile duct, liver, pancreas, duodenum, and related blood vessels.

Anatomical models are educational tools and are not intended to diagnose a medical condition.
How to Choose a Digestive System Model
The best digestive model depends on the structures being taught and the intended educational application. A complete digestive system display may be appropriate for general anatomy, biology, and patient education, while a dissectible or regional model may be better for medical, nursing, or advanced laboratory instruction.
Consider whether you need removable organs, complete gastrointestinal anatomy, a stomach section, intestinal villi, liver microanatomy, gallbladder and bile ducts, pancreas and duodenum, blood vessels, microscopic tissue detail, or digestive pathology.
Models with fewer components may be easier to use for introductory demonstrations. Advanced sectioned, enlarged, and pathology models provide greater detail for professional and clinical education.
Each Holt Anatomical product page provides model-specific information about scale, dimensions, represented structures, removable parts, mounting, and included educational materials.
