Human kidney and urinary system models provide detailed, three-dimensional views of the organs responsible for filtering the blood, producing urine, regulating fluid balance, and removing waste from the body. Holt Anatomical offers educational urinary anatomy models designed for anatomy classrooms, medical schools, nursing programs, urology education, biology courses, laboratories, and clinical demonstrations.
This collection includes life-size and enlarged kidney models, dissectible kidneys, complete urinary system displays, urinary organ relief models, nephron models, glomerulus models, renal microanatomy, and advanced replicas showing adrenal glands, ureters, the urinary bladder, blood vessels, and surrounding structures. Available products offer different levels of detail, scale, labeling, sectioning, and removable components for introductory through advanced instruction.
Study the Anatomy of the Human Urinary System
The urinary system includes the kidneys, ureters, urinary bladder, and urethra. These organs work together to filter the blood, form urine, transport it to the bladder, temporarily store it, and eliminate it from the body.
Depending on the model selected, students may be able to identify the kidneys, renal cortex, renal medulla, renal pyramids, renal columns, papillae, calyces, renal pelvis, ureters, urinary bladder, urethra, renal arteries, renal veins, nephrons, glomeruli, and adrenal glands.
Three-dimensional urinary models make it easier to understand how the kidneys are organized internally and how urine moves from microscopic renal structures into the collecting system and urinary tract.
Human Kidney Models
Kidney models provide a focused view of the external and internal anatomy of the organ. Depending on the product, a kidney may be represented at natural size or enlarged to make small structures easier to identify during instruction.
Models may show the renal capsule, cortex, medulla, pyramids, columns, papillae, minor and major calyces, renal pelvis, ureter, renal artery, renal vein, and hilum. Some models also include the adrenal gland and surrounding blood vessels.
Kidney models are commonly used in anatomy, physiology, medical, nursing, biology, nephrology, urology, and patient education.
Dissectible Kidney Models with Removable Parts
Dissectible kidney models separate into two or more components so learners can examine internal anatomy. A longitudinal or frontal section may expose the cortex, medulla, renal pyramids, renal pelvis, calyces, blood vessels, and beginning of the ureter.
Students can remove and replace sections while practicing anatomical identification and learning how the internal regions of the kidney relate to one another. This hands-on approach supports detailed study without requiring preserved biological specimens.
The number of removable components and the structures represented vary by model. Review each product page for information about sectioning, scale, included anatomy, and mounting.
Life-Size Kidney Models
Life-size kidney models represent renal anatomy at or near natural dimensions. They provide a realistic reference for the size, shape, orientation, and location of the kidneys within the posterior abdominal region.
Natural-size models are useful for general anatomy instruction, nursing education, clinical demonstrations, and patient consultations. Depending on the product, the model may separate into halves or include the adrenal gland, ureter, vessels, and surrounding structures.
Enlarged Kidney Models
Enlarged kidney models reproduce renal anatomy at several times natural size so internal structures are easier to see during lectures and group demonstrations. The enlarged scale can make the pyramids, papillae, cortex, medulla, calyces, vessels, and collecting system more clearly visible.
Some enlarged models also include a schematic nephron or microscopic renal structures to connect gross anatomy with kidney function. The exact scale and dimensions vary by product.
Complete Urinary System Models
Complete urinary system models show the kidneys, ureters, urinary bladder, and associated structures together. These models help students follow the urinary pathway from the kidneys through the ureters and into the bladder.
Depending on the product, a complete urinary display may also include the adrenal glands, abdominal aorta, inferior vena cava, iliac vessels, prostate, rectum, pelvic bones, muscles, or reproductive structures.
System-level models are especially useful for anatomy, medical, nursing, physician assistant, urology, and allied health programs that need to study organ relationships as well as individual structures.
Urinary Organ Relief Models
Urinary organ relief models present the urinary system against a board or anatomical background. This format can clearly demonstrate the position of the kidneys, ureters, bladder, vessels, and surrounding structures while providing a stable model for classroom display.
Relief models may be natural size or enlarged and may include removable kidney sections, bladder components, adrenal glands, major vessels, or reproductive anatomy. They are useful for lectures, laboratory stations, wall displays, and patient education.
Kidney Cortex and Medulla Models
The renal cortex forms the outer region of the kidney, while the renal medulla contains the renal pyramids and deeper portions of the urine-forming system. Sectioned kidney models help learners compare these regions and understand how they contribute to renal function.
Depending on the model, students may be able to identify cortical tissue extending between the pyramids as renal columns, as well as papillae that empty urine into the minor calyces.
Models that clearly distinguish the cortex and medulla help connect gross kidney anatomy with nephrons, blood vessels, filtration, and urine concentration.
Renal Pyramids, Calyces, and Renal Pelvis
Renal pyramids are cone-shaped regions of the medulla that contain portions of the renal tubules and collecting ducts. Urine moves toward the papillae at the tips of the pyramids before entering the calyces.
The minor calyces receive urine from the papillae and join to form major calyces. These structures empty into the renal pelvis, which narrows into the ureter.
Sectioned kidney models provide a clear way to follow this pathway and understand how urine moves from microscopic collecting structures into the upper urinary tract.
Nephron Models
The nephron is the microscopic functional unit of the kidney. Enlarged nephron models make it possible to examine structures that are too small to study clearly on a life-size kidney model.
Depending on the product, represented structures may include the renal corpuscle, glomerulus, Bowman’s capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct, surrounding capillaries, and associated blood vessels.
Nephron models help learners connect renal anatomy with filtration, reabsorption, secretion, water balance, electrolyte regulation, and urine formation.
Glomerulus and Renal Corpuscle Models
The glomerulus is a network of capillaries located within the renal corpuscle. Blood enters through an afferent arteriole and leaves through an efferent arteriole while fluid and small dissolved substances pass into Bowman’s capsule.
Enlarged glomerulus models may show the capillary network, vascular pole, urinary pole, capsule, arterioles, and beginning of the renal tubule. These models help explain the first stage of urine formation.
Glomerular models are particularly useful for anatomy, physiology, histology, medical, nursing, nephrology, and biology education.
Kidney Microanatomy Models
Kidney microanatomy models combine enlarged tissue structures with functional regions of the nephron and renal blood supply. These models may present the cortex, medulla, renal corpuscles, tubules, collecting ducts, capillary networks, and urine-drainage structures within one teaching display.
Microanatomy models help connect the visible structure of a complete kidney with the microscopic processes that maintain fluid, electrolyte, and acid-base balance.
They are useful for advanced anatomy, physiology, histology, medical, nursing, physician assistant, and life science programs.
Renal Blood Vessel Models
The kidneys receive a substantial blood supply through the renal arteries. Advanced models may show the renal artery, segmental branches, interlobar arteries, arcuate arteries, cortical radiate vessels, glomerular arterioles, capillaries, and renal veins.
Models showing renal circulation help learners understand how blood reaches the nephrons, how filtration occurs, and how substances return to the bloodstream following reabsorption.
The amount of vascular detail varies by product. Some models focus on the major vessels at the renal hilum, while microanatomy models may show smaller capillary networks.
Kidney and Adrenal Gland Models
The adrenal glands are endocrine organs positioned above the kidneys. Some kidney models include one or both adrenal glands to demonstrate their anatomical relationship to the urinary organs.
A sectioned adrenal gland may show the cortex and medulla, while advanced models may represent surrounding blood vessels and retroperitoneal structures.
Although the adrenal glands are not part of the urinary system, including them provides useful regional context for anatomy, endocrinology, medical, nursing, and surgical education.
Ureter Anatomy Models
The ureters are muscular tubes that carry urine from the renal pelvis to the urinary bladder. Complete urinary system models show their course along the posterior abdominal wall and into the pelvis.
Depending on the product, the ureters may be shown in relationship to the kidneys, major blood vessels, reproductive organs, pelvic bones, muscles, and bladder.
These anatomical relationships are important for understanding urinary obstruction, kidney stones, surgery, medical imaging, and referred pain.
Urinary Bladder Models
The urinary bladder is a muscular organ that temporarily stores urine before elimination. Models may show the bladder wall, interior cavity, ureteric openings, trigone, urethral outlet, and surrounding pelvic structures.
Depending on the product, a bladder model may be sectioned or included as part of a complete male or female urinary system. Male models may show the relationship between the bladder, prostate, urethra, and rectum, while female models may show the bladder in relation to the uterus and vagina.
Bladder models are useful for anatomy, urology, nursing, pelvic health, medical, and patient education.
Urinary System Models with Male Pelvic Anatomy
Male urinary models may include the kidneys, ureters, bladder, prostate, urethra, rectum, major vessels, and surrounding pelvic structures. These models help learners understand the relationship between the urinary and male reproductive systems.
Depending on the model, the prostate may be removable or sectioned, and the urinary pathway may be shown through the bladder and urethra.
Male urinary models support instruction involving anatomy, urology, nursing, prostate conditions, urinary obstruction, catheterization concepts, and patient education.
Urinary System Models with Female Pelvic Anatomy
Female urinary anatomy models may show the kidneys, ureters, bladder, urethra, uterus, vagina, rectum, pelvic floor, and surrounding structures. These models help learners understand how the urinary and reproductive organs are positioned within the female pelvis.
They can support instruction involving pelvic health, continence, pregnancy-related changes, urinary tract conditions, nursing care, gynecology, and rehabilitation.
Kidney Function and Urine Formation
The kidneys filter the blood and help regulate fluid volume, electrolytes, acid-base balance, and blood pressure. They also contribute to hormone production and the regulation of red blood cell formation.
Nephron, glomerulus, and kidney microanatomy models help demonstrate the processes of filtration, tubular reabsorption, tubular secretion, and urine concentration.
Using models at multiple scales allows learners to connect the gross structure of the kidney with the microscopic units responsible for renal function.
Urinary System Pathology Models
Urinary pathology models may illustrate kidney stones, renal cysts, tumors, urinary obstruction, infection, hydronephrosis, glomerular damage, or other conditions affecting the kidneys and urinary tract.
These models allow students and patients to compare healthy anatomy with diseased or altered structures. Some products may display multiple conditions or stages of disease on one teaching model.
The conditions represented vary by product. Review individual product descriptions to determine which abnormalities and anatomical changes are shown.
Kidney Stone and Urinary Obstruction Models
Kidney stone models may demonstrate deposits located within the kidney, renal pelvis, ureter, or bladder. They can help explain how a stone may obstruct urine flow and cause pain, swelling, or changes in kidney function.
Models showing the entire urinary pathway are particularly useful for demonstrating how stones may move from the kidney through the ureter toward the bladder.
These models support medical, nursing, urology, emergency care, radiology, and patient education.
Models of Kidney Disease
Specialized kidney models may illustrate cysts, tumors, infection, scarring, tissue damage, or other renal abnormalities. Comparative models can help learners distinguish normal structures from pathological changes.
Kidney disease models are useful in medical, nursing, nephrology, dialysis, public health, and patient education. The represented diseases and level of detail vary by product.
Kidney Models for Medical and Nursing Education
Medical and nursing students use kidney and urinary models to study organ location, urine formation, renal blood flow, fluid balance, electrolyte regulation, disease processes, physical assessment, and patient care.
These models provide a durable visual reference for lectures, anatomy laboratories, practical examinations, simulation training, and clinical demonstrations.
Dissectible kidneys, complete urinary systems, nephrons, and pathology models help connect gross anatomy with physiology, laboratory findings, and treatment.
Urinary Models for Urology and Nephrology Education
Urology and nephrology programs can use urinary system models to study renal structure, urinary drainage, bladder anatomy, vascular relationships, filtration, and common diseases affecting the kidneys and urinary tract.
Advanced models may support instruction involving kidney stones, urinary obstruction, renal failure, dialysis, infection, surgery, imaging, and treatment planning.
Kidney Models for Anatomy and Physiology Courses
Anatomy and physiology courses use kidney models to connect organ structure with filtration, water balance, electrolyte regulation, blood pressure, and waste removal.
A complete urinary system model provides an overview of urine flow, while enlarged nephron and glomerulus models reveal the microscopic structures responsible for urine production.
Using both gross anatomy and microanatomy models can help students understand the urinary system at multiple levels of organization.
Kidney and Urinary Models for Patient Education
Healthcare professionals can use kidney and urinary system models to explain kidney stones, infections, urinary obstruction, bladder conditions, kidney disease, dialysis, surgical procedures, and diagnostic findings.
A physical model allows clinicians to point directly to the kidney, ureter, bladder, nephron, or blood vessel involved. Visual explanations may help patients and family members better understand treatment recommendations and the location of a condition.
Anatomical models are educational tools and are not intended to diagnose a medical condition.
How to Choose a Kidney or Urinary System Model
The best urinary model depends on the structures being taught and the intended educational application. A sectioned kidney may be appropriate for general organ anatomy, while a complete urinary system display is better for demonstrating urine flow and regional relationships.
An enlarged nephron, glomerulus, or kidney microanatomy model may be preferable for teaching filtration and renal physiology. Medical and urology programs may benefit from models that include vessels, adrenal glands, pelvic structures, reproductive anatomy, removable parts, or pathology.
Consider whether you need natural-size or enlarged anatomy, a dissectible kidney, complete urinary organs, renal blood vessels, adrenal glands, nephrons, glomeruli, microscopic structures, male or female pelvic anatomy, or disease features.
Each Holt Anatomical product page provides model-specific information about scale, dimensions, represented structures, removable components, mounting, and included educational materials.
