Discover anatomical structures, understand how body systems work, and test your knowledge through interactive learning. Click any organ or bone on the 3D model to inspect its function and location immediately.
Study the function, anatomical location, and 3D morphology of essential human organs. Click Learn more on any structure to open its dedicated reference page.
A muscular pump in the chest. Its right side sends blood to the lungs; its left side sends blood through the systemic circulation.
The central organ of the nervous system. Its interconnected regions support perception, movement, memory, language, and the regulation of bodily functions.
A large organ beneath the right side of the diaphragm. It processes absorbed nutrients, produces bile, and synthesizes many proteins carried in the blood.
The composite organ of respiration in the right hemithorax (spanning 156 bronchial and vascular pieces in the atlas) where gas exchange occurs.
A muscular chamber between the esophagus and small intestine. It stores and mixes food with acid and enzymes before releasing it into the duodenum.
A bean-shaped retroperitoneal organ on the right side of the posterior abdominal wall that filters blood and produces urine.
Static two-dimensional textbook diagrams make it difficult to grasp how deep organs, vessels, nerves, and bones relate in three-dimensional space. Anatomy Explorer bridges textbook descriptions with spatial inspection.
Orbit, zoom, and inspect over two thousand individually modeled anatomical pieces. Transition smoothly from an assembled body to a full exploded anatomical inventory, or isolate a single structure to study its exact morphology from every angle.
Study the human body layer by layer across 15 physiological systems—from the skeletal framework and muscular attachments to arterial, venous, nervous, digestive, and respiratory pathways. Reveal or hide systems individually.
Prepare for laboratory practicals and anatomy exams with structured quiz tracks and spatial identification challenges organized around real FMA anatomical concepts and organ relationships.
Search any structure by anatomical name or Foundational Model of Anatomy (FMA) reference ID. Inspect composite concepts made of multiple sub-meshes, read concise physiological summaries, and track the structures you have studied.
Bones form the supporting framework of the body, protect organs, and provide attachment points for muscles. Their internal tissue also stores minerals and produces blood cells.
Skeletal muscles generate movement by pulling on their attachments. Together with tendons, they move joints, stabilize posture, and produce heat.
The heart is a muscular pump with four chambers. Its valves direct blood forward through the pulmonary and systemic circuits.
These structures contribute to special senses, including sight, hearing, and balance. Their specialized tissues detect stimuli and work with the nervous system to convey information.
The heart drives blood through the circulation. Arteries carry blood away from the heart to supply tissues or, in the pulmonary circuit, to the lungs.
Veins return blood toward the heart. Superficial and deep networks collect blood from the tissues; the pulmonary veins bring oxygenated blood back from the lungs.
Accessible directly in the web browser with zero registration barriers, enabling anyone to study verified 3D human anatomy on desktop, tablet, or mobile.
Reinforce gross anatomy coursework and laboratory dissections. Inspect spatial relationships between bones, muscles, vessels, and visceral organs using standardized FMA anatomical concepts.
Understand how physiological systems fit together inside the human body. Use the Exploded View slider and system presets to see how individual organs assemble into complete functional systems.
Explore the architecture of the human body without complex medical software or account walls. Search common organ names, read clear functional explanations, and inspect structures in 3D.
